These are two different prototype chips made by Chipco. I bought both of them from David Sarles at the last convention. They were used for a camera test in the casino. Here's the interesting part. They are actually paper prints attached to other Chipco samples. The chip on the top of your scan has an "IndoPacific Gaming" reverse. The chip on the bottom of your scan has the fairly common Chipco $2.50 sample chip with the diamond royal flush on the reverse. Hope this info is helpful to you. Also, David had 2 similar $1 chips for sale and 3 similar $5 chips which he kept for his personal collection.
