Webster: "Commemorate: 1 : to call to remembrance."

More Webster: "Limited: 1 : confined within bounds; restricted."

These are two very different terms. For a group of people so narrow in their definition of a "millennium" chip, and the use of the words "token" and "gaming" for example, I am surprised these terms are used so loosely. It is common practice today for casinos to release commemorative chips in "limited" quantities. It is also common for chips released in specified limited quantity to commemorate something. In neither case is it always the case that one implies the other.

In my opinion, if a chip does not specify the quantity produced (which implies a guarantee that no more than the specified quantity will ever be produced), it is not technically a "limited" edition. Personally, I do not see the need to be compulsive about it though, the same as I would choose to call chips that were intended to commemorate the millennium, "millennium" chips, even if they don't say millennium, even if it ain't the millennium, as long as there was clear intent on the part of the casino to commemorate some millennium. It's limited enough if the casino says, "only xxx were made."

Commemorative is easier to determine, but still not cut and dry. The Hyatt set pictured below... are these commemorative chips? What do they commemorate? The lake? Caesars Tahoe chips have a picture of the lake on them. Are they commemoratives? Is this Hyatt set a limited edition? I was told that only 500 sets were made. Can Hyatt make 5000 more sets and use them as the new table chip?
