I also doubt that this will sell unless you do one of the following:
1 - drop the price to $2.50 (and it's still unlikely)
2 - commit that all 100 cards will not be duplicates and drop the price to $3.00 (and it's still unlikely)
3 - commit that all 500 cards will not be duplicates and drop the price to $5.00 per/100 ($25 total)
4 - add in some rares or URs that spark people interest and set the price based more on the worth of those cards
