Garden City in San Jose, California recently changed over their $1 rack chips. Their old chips had different designs on each side, "Garden City" on the obverse, and $1 on the reverse. Has anyone seen chips with the name or denomination on both sides? How "rare" are these?

In regards to two headed chips, can anyone confirm a two sided Trumpeter chip from the new rack $1 chips at Harrah's Las Vegas. I've heard of them, but have not seen them. Again, how "rare" are these?
