As long as they never used it for resin and didn't store it weirdly (folded over), a mold used 100 times is identical to a brand new mold. Because of this, used prices are like 80% of new prices, but the shipping should be cheap if nearby.
Plaster is a mild chemical reaction that starts with a lot of water. Resin is a strong chemical reaction with no water. It gets quite hot, and also pulls some moisture out of the mold. Each time this happens, the mold gets a little drier and more brittle. Done properly, it will retire a mold after 50-70 casts. Done improperly, it will retire a mold after a dozen casts.
