2 Cent Carmine Block Of 4 Unwatermarked. Need Help To Identity Type Of Perf. 11

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?

Image appears to be an offset printing.

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.

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.

Does the stamp raised raised ink?

This is crop from the second right horizontal stamp. I tried to make it a better image view.

The block is a type I engraved, flat plate and unwatermarked. The color is wrong for 461, making it 499. End of story.

Thank you Clark.
Don

I checked it Don, there is no raised ink.

thank you, Clark! I wanted to make sure.

Hi,
I was trying to walk you through the process of determining print type first but Clark was kind enough to ID the stamp for you.
Don

I appreciate it Don. I look sometimes at ebay under Scott 499 and 500, and I saw what was being certified with colors, so I said best to ask. Thank you again!

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!

Actually, all type Ia A140 2-cent stamps are flat plate, just as all type II & type III are rotary press. Type I can be either flat plate or rotary depending on the issue.
