The rarest card in its subset.
Has anyone pulled a 2015-16 Upper Deck Series 2 Hockey UD Game Jersey GJ-DG Doug Gilmour trading card? If so, did you pull that card from a blaster, retail, hobby or e-Pack release?
That particular card was inserted into 1:588,924 packs, on average. I haven't seen a copy of that card for sale or trade on eBay, COMC, or Upper Deck e-Pack.
It's going to be interesting to see what that card sells for. I'm guessing at least $500 considering three copies of the lower tier UD Game Jersey GJ-SY Steve Yzerman card, which was inserted into 1:18,846 packs, on average, sold for $74.99 to $99.23.
