One of those is the 2012-13 Score Black Ice cards. I fired up the google machine and couldn't find much concrete info on them as far as print runs and availability. Eventually I came upon an old thread on Sports Card Forum and posted, wondering if anyone had any additional info. Unfortunately, not too much.
My own research on available and sold cards, posted in the thread, was this (numbers are as of November 17):
"I checked COMC and there are only six of these available with asking prices ranging from $8.75 to $39.70. There are four others on eBay with asking prices of $4.46 to $19.99. In the "sold" history, I found two cards that sold for $2.97 and $4.46. Finally on Sportlots, I found five available. The asking prices were $1 (I have already purchased this one), $9.99 and three at $10."
I checked COMC over Thanksgiving weekend in hopes that someone would heavily mark one of these down. No luck. I've decided to "collect" these when I come across them cheap. The only one I've bought arrived on Monday.
Shipping from this Sportlots seller was the same up to four cards, so I bought the additional ones from him for 18 cents each. Seems foolish not to take advantage of that.
If you have any of the Black Ice cards that you have no use for, let me know!
