A visepunch cuts or presses a circle mark into the dice (Just a plain mark with no gold foil or paint)and is the most common casino cancelation.

A Gold hotstamp "O" is a factory cancelation.

In this pic the 4Q dice have the gold hotstamp "O" and the Resorts have the plain "VOID". Both are factory rejects (the 4Q have scalping lines on them)

The other 2 pair have been casino canceled with diferent size vice punches.
