I'm not chasing Cup or any new stuff. I've been following the prices and demand on 89-90, 90-91 and 91-92 PSAs. Not only are an insane amount of cards from that time are going up, particularly hockey and non-sport like Marvel cards, but it's not just PSA 10s that are selling. PSA 9s and 8s are selling for good money, so are raw copies, and it's not just the top key players like Jagr, Hasek, Forsberg and Lidstrom. Other good players' RCs, assuming they have cards in sets such as UD, OPC Premier and Parkhurst, such as Roenick, Belfour, Brind'amour, Modano, anyone good from that time are selling for triple digits for PSA 10, over 30 bucks for PSA 9 and even PSA 8s sell for cost of PSA submission. The Score guys (Brodeur and Lindros) are selling too, but the prices of those cards along with Pro Set RCs are all lower by half across the board.
So therefore, it's also a matter of time before the junk wax sealed boxes from that time will go up by several multiples, as people from my generation of collecting want to open boxes to hit pack-fresh PSAs. Card lots of 2 to 20 copies of the same card are moving as people hunt down copies to get graded. This is following the Pokemon trend and I think other cards like basketball's old Hoops and Skybox may be following.
As of last week, the huge news is the 1990 Marvel S1 from Impel, the set with the first hologram cards, now has boxes selling for $3000 a box (no I did not mistype), and has settled for around $2500+. Copies of single cards of Stan Lee and any major movie hero like Spider Man and Iron Man are going for hundreds in PSA 10, up to $800 depending on the character. People are buying up the boxes and cracking them to hunt for PSA 10s. (Last month, Marvel boxes shot up to like $500...three months ago, they were like $100 to $150.)
Next up will be hockey. OPC Premier boxes are already there as people are trying to get copies of the UD 1 Ken Griffey Jr. of hockey, the 90-91 OPCP Jaromir Jagr. Raw copies NM sell routinely for around $40, PSA 8s, for more than that, PSA 9 around $150, PSA 10 for $700 to $750ish.
But what's getting me excited is the routine triple digits PSA 10 UD cards are getting like the base Rod Brind'Amour from 90-91 UD...a base copy sold for around $3 ($1 plus $2 in shipping...this card never booked for more than $2 even back in 1991) and a PSA 10 sold for almost $100.
A Dominik Hasek 91-92 Parkhurst English PSA 10 went for $300+ while a French PSA 10 went for just about $400. You get the idea.
