I found this on an exonumia site. I often wonder if casino chips are in that group, although most items are metal, tokens, medals Etc. Slot tokens might fit, but our plastic/clay chips probably aren't? Meanwhile, here's an interesting viewpoint from a very educated collector. (with a link to a link to his site) Most of this applies to casino chips, substitute for the word token or tag.

A fake is a counterfeit, generally a cast copy of a genuine original. Some deceptive fakes of original Slave Tags have been made with new dies. It is against Federal law to make fakes or counterfeits of original items. A number of coins, tokens and medals have been faked. Some expensive coins have been faked by creating copy-dies.

A fantasy is a piece that never existed years ago and implies it is old. Most fantasy pieces sound too good to be true, and generally are! I have also listed some suspect pieces that I highly doubt are original items, but I must see to be able to determine (they are listed as doubtful). Fantasy pieces can be struck, cast or engraved. A number of fantasy pieces have been created by ordering from legitimate manufacturers, with good quality die work and design. Just because it looks good does not mean it is, and just because it looks shoddy it does not mean it isn't genuine!
