Intended primarily for sale to collectors, the original issue of 25,000 sets was valid for postage for only three days.
Excellent litho forgeries exist. Given the limited numbers issued and short validation dates, the catalog values do not reflect the rare originals but the vast quantity of forgeries
Genuine stamps
The original stamps have different control numbers on them.
Forgeries
The forgeries are easily distinguished by 2 main features
- the forgery has a dot placed immediately between and below the 93 of 1930. Below the dot are 2 equally spaced dots and below them is a single dot directly below the first one.
- The top right corner line joins the ones below it while in the genuine it does not
The control number on the reverse of the forgeries is always A000,000 in blue or black.
