Good Day to everyone The pictures are scanned at 1200DPI, and the back shows no watermarks. It has to be a type 1 or type 1a, since only one line in ribbon shading. Is it a Scott 499 or something else?
Based on the scans, can someone tell me which one may it be, a type 1 or a type 1a?
Check to see if stamp is non-engraved offset printing. (This means that the ink lies flat on the paper of the offset stamp. If you hold the stamp at a very sharp angle to a light source, the color on the stamp will almost disappear. This is just the opposite for the engraved stamps. Engraved stamps typically have raised ink, you can often feel it with your finger; compare with other stamp which are known to be flat plate engraved stamps.)
If it is offset, then perf 11 choices are 526, 527, 528, 528B, and 528A. Don
I did not think it was an off set since the Scott 526 would have only as a type 1V. Which means the top line of the toga robe is broken, and the shade line in the button would have "C11D" look. The toga lines are not broken or has that "C11D" in the button.
Another technique that some use to distinguish between engraved (flat plate & rotary) or offset stamps is the "foil test". Take a small piece of aluminum foil & place it over the surface of the stamp. Then gently rub your finger across the foil for a few moments. Then remove & reverse the foil & check it for any impressions. Engraved stamps, due to the raised ink on their surface, will leave an impression of the stamp design in the foil. Offset stamps will leave no such impression. Of course, in this particular instance, you have Clark's (cfrphoto) opinion to go by. You will find no higher philatelic court.
Thank you, JL. another excellent technique expressed. If I am correct, the Scott 500 (1a) can be both. Rotary for unused condition stamps and only flat plate for used condition stamps. Yes, Clark is excellent as well as others too! Thank you all!
