Selling
Drop cards on the 
Sell box at the end of your shop row, or on a 
Market, to sell them for emeralds. A card's tooltip shows what it's worth, and nearly everything sells for at least 1 emerald. Diamonds are for crafting and can't be sold.
Emeralds and books don't take up card slots, so selling is also how you make room. See Card Slots.
Trading Post
A 
Trading Post swaps 9 emeralds for an 
Emerald Block and back, and shops count an Emerald Block as 9 emeralds. It sells packs too.

Wandering Carpenter
After your third supper a Wandering Carpenter starts coming by. He trades Table Leaves for emeralds, and each Table Leaf makes your side table bigger. See Table Size.
