And fortunately 3 pieces now are found in the first 3 collections. What a unique event.

Just in case there was any confusion, I don't have one. The 3 Polushkas referred to earlier in this post that I, numrare, and KBK were going to put together were all different years, each extremely rare. I don't know of 3 of KBK's new coin, though numrare says he knows of them.
