You guys are all clueless as to how this is really done. First of all, nothing is laser cut - that's the biggest myth in the hobby period. The cutting is actually done by hand (as any laser leaves clear burn marks along the side of the card - after all, that's how laser's cut) with a tool that similar to what architects use while drafting. Also, there were only a handful of sheets available to be cut up into 9.5's or 10's. In fact 75% of all the high end OPC graded rookies out there (Martin Sports, KBboyboo etc.) all came from the same place - an auction several years back of uncut sheets dating back to the 1970's. The auction was of the old OPC Plant managers estate, as he had kept 2-uncut sheets of every year of OPC since he was hired in the early 1970's. They were all in his garage when he died, and his wife auctioned them off for over $250,000. Jason Martin won this auction.
Therefore there's only a handful of truly vintage 9.5's and 10's out there, and since there are no more uncut sheets that anyone is aware of (although it's possible there's 1-2 lying around in someones basement somewhere), there will be no more 9.5 or 10 graded 1970's rookies. The 80's stuff is a little more available though - but either way - the supply is not endless as some of you have mentioned. These cards are somewhat unique due to the process that gets them to be graded so high, but they are 100% authentic cards non the less, and there is a very limited supply at the end of the day. Good lukc trying to pull a 9.5 Marcel Dionne rookie out of a pack.
