I know that three variations of this chip exist. My problem is that the chip on the left does not look like any of the three listed or pictured in The Chip Rack. The difference between the three shown and the one on the left is the space between the top of the $1 and the bottom of the lion. On the three listed, the space is the same. On the one on the left the space is much larger. Does anyone have any ideas about this? Thanks in advance.
