Bought some rare cards want opinions!!! Red foil sheets from marvel IV

Hello, I bought all three uncut foil sheets from the san diego comic
con off ebay for $78.07. They are the uncut red foil sheets limited to
1200 per sheet. The set is 3 sets of 3 and they came out in 92 I
think. For the marvel series IV. I know these cards are very hard to
obtain seperatly let alone the set. I was just wondering if I paid a
fair price. I have never even seen them sell on ebay before. They are
mint and still in their lucit cases. Let me know whatcha think!!!
