Since there's no way to look at the overall market for cards it's hard to tell what price levels different rarities are selling at in general. Post what price you are picking for different rarity levels (and if they're selling) so people can get an idea of what prices to choose! For me:
Common: .02
Uncommon: .10
Rare: .20
No listings above Rare yet. Basically I'm listing at double the junk price. No sales so far.
