is always in search of threads to the past and from time to time, little gems like this pop up! Your decission to hang on to these chips is not an issue, but as you do, please keep in mind that exposure to light bis never good and exposure to heat is a absolute killer! Also avoid water, but otherwise, these things are pretty sturdy artifacts to what once was.
Take care, feel free to venture back, and thank you for the scan and quantity information as it sometimes helps us understand the games offered or different ownerships of the same place!
Thanks!
