This would be a fantastic set for anyone wanting to "step up" from cheap chips to real compressed clay chips. Under $1 a chip, plus the cool case is just icing on the cake. I would keep the $10s as is for the following reasons.
I mentioned this previously in another thread to someone looking for a "beginner" set. This set could easily be built up over time. These colors and 312 spot pattern are very common in chips from this vintage. I suspect someone keeping an eye on the classifieds could find another chip, maybe a solid, to use as a frac. Then add another rack of $1s and you have a fully functioning "full table" set. Because even though one rack of $5s is a bit short, the extra rack of $10s makes it very playable. Also, most of the various older ASM/Burt molds can play well together. Meaning you could find chips with the same color, but a different mold like horsehead, hub or really any of the older molds, and the chips would likely match up in size and thickness.
