I came across these $1 Boomtown chips today and noticed that the central blue/white patterns were strikingly different. Upon further inspection the horses and back wheel of the carriage also looked a bit different. Below are scans of both chips and both are in good shape with sharp edges with little wear. The blue/white pattern on the first chip looks as it does in the scan. The blue/white pattern on the second chip almost seems to move when you rotate it in your hand like it’s some 3D effect.

The first chip one looks to be CG00492. Does the second appear to be a different variety to anyone else?
