Makes me think back to that magical day 6 years ago when I picked up three 16th series packs at the Allentown show for $20 apiece. They were probably already worth $150-200 at the time!
When I first re-entered the hobby and attended a few NJ & Philly shows in 1997-98 (they were still held at hotel expo rooms at the time), there was a seller with 14th, 15th and 16th packs for sale, and he had considerable inventory of each. He charged $5 a pack for 14th and 15th, but only $4 a pack for 16th!!! Reason he gave was that some of the 16th packs were "miswraps" as he put it, in that they were missing the puzzle piece card. But if I remember correctly, some of the packs missing the puzzle piece had an extra sticker! I was focused on the 15th, a sentimental series for me, and only bought a few 16ths, having no clue they were harder to find and would eventually skyrocket in value.
