What constitutes a "limited edition" chip. Does it have to say "Ltd" with the number issued?

The reason I'm asking is because I've seen the following $1 Four Queens chips shown as "house chips" as well as "limited editions":

*Halloween (internet address in orange & black)
*Christmas (intenet address in red & green)
*Internet address chip
*First edition reproduction H&C
*35th anniversary reproduction with name in mold

Anybody know of other conflicting designations?

Any comments would be appreciated.

Thanks for your help.
