Wow!
I was thumbing through the Beckett yearly book and trying to get a reference to that /155 print run (to help) and what it came out of and no such luck. It does post the /875 run and the /50 parallel. As Retail, it lists a /225 run (which might have been on the packs or advertised as such) but nothing on the other /155 run. If you didn't have it, I would not have known it existed unless I pulled one.
The collectors with collections like the above and most of the variation player sets that i have seen on this thread are some of the best resources to this hobby. Thanks for sharing!
