Do you have "Artwork" files for some of the chip designs? (Rough drafts, final designs, notes on color, production, dates, etc.)
That kind of information / files would be collectible and/or of historical interest in donating to the museum.

Especially artwork files for the early Chipco designs that resulted in the El San Juan, Harvey's, Harrah's and President Riverboat commemoratives.
(Those are the earliest that I recall). But also other artwork files, such as the Desert Inn series, the Main Street H&C Las Vegas, the SBM Monte Carlo Roulette set, and more.

If available, there would probably be a "feeding frenzy" for some of this material. I can think of several collectors -- myself included -- that would LOVE to obtain the artwork files for the SBM Monte Carlo roulettes!!
