I decided to share one sample from an art tour and a few samples from different pin sets. The last one is high number and sure looks different to my eye from the others with a "4" shaped J. The next to last has a loop at the top of the J and is also high number. If I had to guess, at least the last 500 were farmed out but I'm less certain about the earlier ones. I think I lean towards the conjecture that he split the stack in two or thirds and did the low numbered ones...
