Here are just a few of many, many examples in which a minor alteration or correction
was made between subsequent releases of very similar casino chips...

Zip code was changed from 19912 to 19952 or vice versa

Queen of New Orleans became the Hilton Queen of New Orleans

The word "casino" was added to the Yavapai property name

First mint mark was "CI" - the next one was "GO"

One says "TM" beneath the name - the other says "R"

Oops... Royal became Royale

Sometimes the differences are not so subtle

Got any favorite examples of "minor alterations" you'd like to share?
