A Question On # 10 Vs # 11.

here is a listing on hip stamp.

https://www.hipstamp.com/listing/10...426/11074579

Said to be ex-chase. Would anyone be kind enough to offer an opinion on this listing and the ex chase history?

Thanks in advance.

Stamp is priced too high but identified sort of correctly. It's a 10A. If there were any defects they wouldn't be disclosed. Ex. Chase? Look who's making the claim. I have Ex. Chase material but I can also prove it. Find a better dealer.

How's that?

I think that is great and thank you. Might I offer this listing, also on hip stamp which might be worthwhile?

many years ago I actually got the Chase book form the library and learned a little. Retention is not that good after 40 years and these links are helpful. With time and good health I am learning more about these stamps. Thanks for the input and understand there is much to learn, and much to be thankful for.

The looncove stamp is alsoa Type II, meaning it would be a 10A/11A. I don't doubt that the stamp is an orange brown 10A. I don't know the seller but he/she is also depriving you of an opportunity to see the back of the stamp and perhaps the condition for yourself.

Ex-Chase 10/10A/11/11A stamps are not hard to come by. Chase often wrote the position on the back, but so have hundreds of other collectors. These stamps that have not been bought or sold in a while are often misidentified if they are type II since type II stamps only got a major Scott number a decade or so ago. If Chase would have identified it, he would have called it a Type II 10 or 11. Ask the dealer if the plating info is on the back and then it will be very easy to confirm if it is a 10A vs 11A.

Chase plated stamps for other collectors, probably thousands of them. Finding Chase's plating notation on the back means absolutely nothing in regards to the provenance of a stamp. It does, however, give the unscrupulous an opportunity to exagerate the desirability of an item.

The old Type I included todays Type I and II.

Type II stamps used to be what we now call the Type III.

The Type IV stamp used to be a subtype of Type II and was called the Type IIa, sometimes referred to as "Plate 10 group" stamps and come from Plates 10 and 11.

Your responses are most helpful and thank you.
I am pasting in the stamp smarter link on the stamps for all as it is the most concise resource I am aware of. Thanks all!
