How much is a bersa 380 worth?

Worst case - federal prison time Best case - 500 USD

You can buy a new one at Academy for $279, and used guns are running close to new prices if they're in good condition. It's kind of an obscure Argentinian brand, so probably $225. I personally...

100-20000 USD depending on EXACTLY what you have, condition, history, accessories, finish, box, papers, etc..

New, a basic model runs between about $250 and about #325 depending on where you buy it. Used, they usually go for about $200 in good condition.

100-300 or so
