For the first time, the catalog shows reference prices.
It is not possible to determine an objective price for a cover document. Every collector has personal perceptions here. However, in order to achieve a reasonable price display, the following ideas were implemented:
First, a stamp is evaluated for itself, i.e. only according to criteria that can be determined on itself. This includes:
- Readability (good, less good, bad)
- Age (the older, the more valuable)
- Market availability (the rarer, the more valuable)
- Hand or machine postmark (machine with surcharge for better legibility)
However, this maximum postmark value is only intended for a postmark on a document with the best possible equipment:
- Postmark is legible and has an occasion related to chess
- Chess stamp is issued on this occasion
- Illustration represents this occasion
- Postmark is legible and has an occasion related to chess
- Chess postmark is issued on this occasion
- Illustration represents this occasion
If this best possible condition is not achieved, the price will be devalued.
Private postmarks and meter slogans were not included in the assessment.
A very detailed description of the evaluation procedure is enclosed with this catalogue. It should be noted that version 1 of this presentation was already published as a basis for discussion in GSM Newsletter 232 in November 2021.
