Actually the die on the left is correct and if you turn the six on the right hand die to the front, it would match, except the six is rotated 1/4 turn. Which is probably just another variation on what you said. (G) What's funny is "you made me look" and I found that I have Excalibur dice with the three spot and the two, at different angle, if the dice are placed next to other "standard" dice. Interesting. However I could find no examples where the six was as in the chip depicts on the right.
