George VI stamp value: identify Britain's definitives

Start with the British definitive, not just the king

For an ordinary British George VI definitive, identify the full design before copying a value. The checked upright-watermark 2½d blue mint offers were GBP 0.25 each, while two differently described 10/- Arms offers were GBP 180.00 and GBP 27.00. Those are specific dealer asks for unmounted mint singles, not the value of every stamp showing George VI.[4][6][7]

This guide covers Great Britain's ordinary definitive designs encountered in the 1937 to 1952 period. It does not cover every Commonwealth portrait issue, overprinted British stamp or commemorative. Klaseboer's reference separates the everyday head designs and large high values from the Coronation, Victory, Silver Wedding, Olympics and UPU issues.[1] A portrait and a familiar denomination are not enough to put those commemoratives into the same price comparison.

Photograph the complete stamp, including all four edges. Copy the denomination and any overprint exactly, then note whether it is a small portrait stamp or a larger high value. If a territory name or surcharge appears, stop using the ordinary unoverprinted British comparison. Keep an album label as a clue, not a confirmed catalog identity. A useful record can say that a watermark or shade is still unresolved.

Read 2½d as old pence, not decimal 2.5p

The currency heading in Klaseboer's British reference gives 12 pence to one shilling and 20 shillings to one pound.[1] Here d denotes old pence. A George VI 2½d is two and a half predecimal pence, not a decimal 2.5p stamp. Write the actual unit beside the number. A search box or image filename that abbreviates it as p does not change the inscription on the stamp.

Read 2/6 as two shillings and sixpence and 10/- as ten shillings. The £1 inscription is the historic face value, while GBP 13.95 in this guide is a present dealer asking price for a particular 10/- offer.[1][8] These are separate fields. No conversion of the old denomination into a modern collector value is used here. A face value does not tell you the gum, watermark orientation or retail price.

For a beginner's description, write blue 2½d George VI definitive rather than blue 2.5p stamp. Next add the proposed colour group and condition. This makes the query narrower without pretending that the exact catalog entry is already established. The illustration below contains blank notes and unmarked disks, not reference coins, genuine stamps or a historic exchange-rate chart.

Separate dark, light and changed-colour low values

The reference groups the first everyday heads under 1937 dark colours and the lighter low values under 1941. It lists the later changed colours separately.[1] The dealer calls SG466 2½d ultramarine a 1937 dark-colour upright-watermark stamp and SG489 2½d light ultramarine a 1941 light-colour upright-watermark stamp.[4][5] Both checked offers were GBP 0.25. A lighter appearance therefore does not automatically mean a higher price.

The later colour group includes a red 2½d rather than the earlier blue 2½d. The dealer category uses a 1950 heading for changed colours, whereas EARS uses 1951 for its new-colour heading.[10][11] Those broad headings do not establish the first day of every denomination. This guide does not resolve that date difference by assigning one release date to the entire group. Use the exact stamp's current catalog entry when a date is needed.

Compare shade under consistent neutral light, with the unedited image saved. A warm lamp, scanner settings, fading or a heavy cancellation can make a stamp look different. Do not rename an altered or badly photographed stamp as a catalogued light-colour printing. The relevant printed design, denomination and physical paper checks still need to agree. Keep a doubtful shade provisional rather than choosing whichever listing has the larger price.

Use the genuine scan as a design reference only

The Commons file below describes a scan of a United Kingdom 1937 2½-pence stamp, scanned by Stan Shebs. Its exact image file is marked public domain with no attribution requirement.[9] The portrait faces left, POSTAGE and REVENUE flank it, and the denomination includes a printed d. The visible cancellation crosses the left part of the blue design. The specimen is not any of the dealer's priced mint stock.

Use it to compare the layout, crown, portrait and value tablet. It does not prove the watermark or gum of your stamp. It is also not a colour-calibrated shade standard. The downloaded original is 450 by 542 pixels, so enlargement cannot supply microscopic information that the file never contained.[9] Our padded derivative retains the whole scan without trimming its perforated edges.

A similar portrait on a different frame may belong elsewhere. The Wilding guide covers Elizabeth II portrait definitives, while the Seahorse guide covers George V's earlier high-value family. Do not apply their papers, printings or price samples to this George VI head simply because all are British stamps.

Check watermark orientation before a variety price

The two 2½d offers in the price table explicitly say Watermark Upright.[4][5] That qualification matters. EARS explains inverted watermarks in booklet production and sideways watermarks associated with coils. Its dark-colour sideways discussion includes the five low values and identifies the 2½d as a later addition than the others.[3] A rotated portrait photograph is not an inverted watermark identification.

Use the watermark identification guide for safe physical inspection. Record both the mark and its orientation relative to the upright printed design, and keep gum condition separate. A front photograph rarely settles that comparison. If you cannot see the mark safely, note it as unconfirmed and compare only provisionally. Do not use the price of an inverted or sideways entry for an unresolved upright-looking stamp.

A single trimmed edge does not prove coil origin, and an album note does not authenticate a watermark variety. Retain joined stamps, booklet margins and leaders where present. Those objects may help explain format but are different sale units from a loose single. The dealer's suffixes and wording should be copied with the catalog name. Use the catalog-number guide before assuming that a seller number belongs to the same system as an old album label.

Separate Arms high values from the 1951 pictorial group

Klaseboer separates the larger Arms definitives from the later pictorial high values. EARS describes the 1951 group through HMS Victory, the white cliffs of Dover, St George and the dragon, and the Royal Arms.[1][2] A 10/- blue stamp can therefore belong to a different design group from another 10/- blue stamp. Match the subject and layout before treating the denomination as a comparable.

The dealer's SG478 dark-blue Arms offer was GBP 180.00, its SG478b ultramarine Arms offer GBP 27.00, and its SG511 1951 ultramarine high value GBP 13.95, all unmounted mint.[6][7][8] These three asks demonstrate why blue 10 shillings is too broad a description. They do not demonstrate a realized-sale premium, and they do not let a screen photograph prove the expensive shade.

EARS describes the earlier high-value paper with a block GviR and crown watermark and illustrates a GviR watermark for the 1951 group.[2] That is high-value evidence, not a rule to transfer without checking to the small heads. The source has inconsistent introductory date wording and a printer attribution not adopted here. No precise earlier issue day, printer certification or watermark-based authentication is inferred from it.

Compare five exact mint offers checked today

GB Stamps Online displayed these five single-stamp offers on 14 October 2026. Each product page stated Stock Status: In Stock and Unmounted Mint, but did not disclose an inventory count. Its text described the image as Generic Image.[4][6][8] These are product-level asks, not unique photographed stock specimens, completed sales or evidence that a buyer can order an unlimited quantity.

GBP is the original currency used for the pound-denominated observations. The site's currency selector explicitly labels GBP as Pound Sterling.[10] No dollar conversion is shown. A US reader should retain GBP in the comparison and obtain delivery terms separately. We did not complete checkout, test delivery, establish the final tax total or buy a stamp. The table is not a delivered-price quotation.

The numbers in the product URLs are listing identifiers; SG466, SG489, SG478, SG478b and SG511 are the seller's Stanley Gibbons Concise references.[4][6][8] Keep those fields apart. Do not divide a set ask into imagined single prices or apply a mint-single ask to a used stamp on an envelope. If a listing changes, retain the observation date and recheck rather than presenting the old amount as a live guarantee.

Match gum, damage and cancellation to the comparison

Unmounted mint is the dealer's condition description for every offer in this table.[4][6][8] It is not a description of the used scan or of your album stamp. Examine the reverse when safe and do not assume that an unused-looking front has untouched gum. A hinge mark, thinning or regumming question needs its own note. No independent physical grade or certificate was established for these offers.

Use the condition guide to record missing teeth, folds, tears, stains and visible repairs. Do not clean or recolour a stamp to match a listing. A stamp with obscured design detail is harder to identify; that does not make it a scarce shade. Keep the original photo and record which details the cancellation hides before asking for a specialist opinion.

Keep covers and joined multiples intact. These single asks do not value a postal route, readable town cancellation, booklet pane or cylinder block. A later postmark dates use, not necessarily printing. If an item has a potentially interesting postal context, compare whole objects with similar context rather than reducing it to the ordinary loose-stamp price shown here.

Leave commemoratives and overprints outside this table

The 1937 Coronation has an event inscription, the 1940 stamp centenary pairs Victoria with George VI, and the 1948 Silver Wedding is separately listed in the reference.[1] A blue £1 Silver Wedding stamp is not the brown ordinary £1 definitive. The same king, year or high face value does not erase the difference. This packet intentionally provides no commemorative valuation.

The reference also lists British designs overprinted for overseas postal uses, including Kuwait and military administrations.[1] An overprint or a surcharge changes the identification question. Copy it exactly, including its unit, and use the appropriate territory and issue entry. Do not erase an overprint from a photograph to obtain a British match or assume that every added inscription is genuine.

A suspect alteration, propaganda imitation or unusual variety needs specialist evidence rather than an app's visual similarity. Keep the claim narrow and explain the unresolved feature. The ordinary British prices here cannot authenticate an overprint, a scarce watermark or the printing of a stamp that has been cleaned or repaired.

Save a George VI record that can be checked later

Save the full front, a safe reverse image, the old-pence or shilling denomination, low-value or high-value design group, colour description and watermark status together. Record the condition as observed rather than borrowing the seller's grade. For a comparison, attach the original GBP ask, catalog publisher, product ID, sale unit and date. Mark a generic listing image as generic.

Stamp Value Identifier & Scan can suggest an identification from a photo, answer follow-up questions and keep discoveries in a visual collection. Use it to organize George VI head designs separately from Arms and 1951 pictorial high values. Its estimates are collector research context, not official authentication, certification, grading or appraisal. A front scan cannot confirm hidden gum or a watermark orientation.

The app has a free tier on iPhone and Android. Save the proposed group first, then update it when a physical check resolves the watermark or shade. If you plan to sell, gather matching realized-sale evidence or request a specialist opinion instead of treating a retail ask as a buyback offer. This preserves what you know and makes the remaining question specific.
