New 1875 Twenty Cent piece added to my collection....counterstamped....

I finally got my first twenty cent piece. I have been looking for an 1875 Philadelphia mint example for a while. It has AU details despite the counterstamp and blue and copper album toning. The counterstamp says P. LEAS and I think it adds nice character to the coin. Can anyone tell me about the counterstamp? Also, looking for feedback on the coin. Thanks.

It's a nice coin, but I know nothing of the counterstamp.
Obscurum per obscurius
Either way it is a very nice coin, perfect for a Danso album.
Does anyone have the Brunk book on merchant and privately countermarked Coins and if you do, can you look it up for me??? Please.

Well, that's rather the OP's question too.
I dig the counterstamp! Adds a bit of mystery to what is otherwise a nice but mundane coin.
