If you turn the token over like you would a U.S. Coin the design opposite side is now upside down. The token must be turned from side to side, left to right, for the token design on the opposite side to be right side up. This refers to the Company that minted or produced the token. This is the side of the token which usually depicts a design not related to the casino. This refers to a token which has a frosted appearance on the designs with the flat areas having a mirror like finish.
Frost occurs on tokens which are struck when the dies being used are new.
Frost wears off as the dies are continued to be struck. Since Frosted types will likely be found on most tokens they will not be reffered to as a variety and not listed separately in the guide.
