Garden City $20s are the most worn chips I've ever handled, but the $10s I have are only moderately broken in. A little nicer than most GV primary $25s, a little more worn than Par-a-dice $25s. The orange spot is especially nice. I only have a barrel of each of the GC chips though. Just ordered 2 more barrels of $10s to use instead of $20s in my micro cash set.
Outpost $20s should not cost anything close to the "best offer" price in that auction. Though it is hard to say for sure since there haven't been any rack quantity sales in quite some time.
