BELGIUM 1912 DEFINITIVE SERIES POSTAGE STAMP, 10-CENTIME CARMINE ON BLUE FRAME, CANCELLED 'MONS S-GENERAL': IDENTIFICATION
This is a used postage stamp from Belgium, clearly identifiable as part of their definitive series from 1912. The central vignette features a 10-centime denomination in carmine, framed by an intricate design in blue. The cancellation is a rather heavy black rectangular box featuring 'MONS S-GENERAL / 20 JUIN 1912', which marks its usage on June 20, 1912, at the Mons post office S. General branch.

Philatelist
The stamp's country, denomination, and precise date of use are all clearly visible and identifiable from the images. The design elements are consistent with known Belgian definitive issues from the early 20th century.
KEY EVIDENCE
- 1Clear 'BELGIQUE' / 'BELGIE' inscription at the bottom identifies the issuing country.
- 2Central denomination '10' clearly indicates the face value in centimes.
- 3Cancellation '20 JUIN 1912' provides precise date of use, confirming a 1912 definitive series issue.
- 4Dual-color printing (carmine and blue) is characteristic of specific Belgian issues of the period.
- 5The 'MONS S-GENERAL' cancellation indicates a specific postal location.
WHAT WOULD IMPROVE CERTAINTY
- →Measure perforations with a perforation gauge to determine the exact gauge, which can aid in precise catalog identification.
- →Examine the reverse for gum type (original gum, regummed, no gum) and any thinning or repairs.
- →Check for watermarks, often crucial for distinguishing among similar early European stamp issues.
- →Consult a specialized Belgian stamp catalog (e.g., Scott, Stanley Gibbons, Michel, Yvert) to confirm the exact catalog number based on color, perforations, and watermark.
CONDITION & GRADE
Condition
The stamp is used, as evidenced by the clear cancellation. Centering appears to be good to very good, with the design well within the perforations. However, the cancellation is quite heavy and obscures part of the denomination and design elements, which can affect its aesthetic appeal and value to some collectors. The perforations are mostly intact, though some very minor blunting might be present on the right edge.
