The chip on the left I picked up in Vienna...
is the chip on the right an earlier issue?
Or did it maybe come from the Bond Casino in Romania?

The chip on the left I picked up in Venice...
is the chip on the right as earlier issue?
Or perhaps a prototype or sample of some kind?

I picked up both of these chips in Linz, Austria...
is the chip on the left (an earlier issue) different enough
from the chip on the right (a newer issue) to warrant a
separate listing on the ChipGuide?

Thanks in advance for your thoughts and opinions.
