I do not know Shane but I have reported this monopolistic activity to the DOJ

Sportscubz
 

I Purchased a Jeter and a Bonds from the OP. And I think down the road they will rank up that a in rarity with Dice game etc. The players Jeter, Griffey Jr., Bonds, Mcgwire..etc. And those that collect players will always have them on want lists. Time will tell.
I have an unopened box of Yankee / Mets Double headers. But no unopened examples. As for the HSN stuff the 1990 boxed sets are scarce but not rare. 85 minis rare 80 coins rare,

The Sportzcubz are tough. I just missed on a Piazza on eBay little while back.

1990's toughies
 

The 1997 Topps Pro Shooters marbles are real tough.

I picked these up last year, 1992 Topps Round Trippers, seller thinks they 1/1 and I'm starting to believe it too.

I have picked up a few of the cards listed here as types-nothing easy about some of them and they can be on par with the "golden era" tests in terms of difficulty. Not all of them but it seems like early to mid 70's tests are generally a little easier than late 60's, then after a fallow period the 80's tests were a little easier still before the late 80's and 90's kicked off and brought some real tough ones. Even that late, Topps always kept it interesting with the tests and proofs, didn't they? If Topps had tighter security over the years, I wonder how many of these we would even know about?

The Piazza (as well as others) were mine.

:D

Do you have another you'd like to sell?

The only Piazza that I have left is in my complete set.

I agree on those Round Trippers. I have 3 Cardinals. I think an Ozzie Smith was sold that I didn't see and missed out on. That means I will probably never see another.
