Here are 3 (somehow) related scans:

Scan 1 is the obverse of the 1 euro chip from Cercle Wagram in Paris... scan 2 is the
reverse side of the Cercle Wagram chip... scan 3 is a UFC - the front and back are the
same - there's no other identification on the chip... can anyone give me a lead or any
info on the mystery chip? Thanks for looking.
