Considering my limited chip population for doing the survey, I'm putting this out for others to check.

I found that all of my assumed real, Nevada mold chips have the cards impression backed by the dice. While all of my Suspected remakes and Borlad chips of the Nevada mold have the dice backed by the dice and the four aces backed by four aces.

Consider it a theory... nothing more.

If it holds up to every other example, we might have a way to ID Borland chips. If it doesn't, then it's an interesting variation on the chip molding process.

Just take the chip with the 4 aces at the top and dice at the bottom. Then rotate the chip (left to right) and look to see if the same symbol is on the reverse, in the same position.

The old chips I have, the design is the opposite on the back. Borland suspects, the design is the same.
