I have an opportunity to buy some broken craters. The orbitals are broken. The part that slips into the nose bridge looks like it broke off clean. I know there's no way to fix it but there are several like this, some left broken, some right. I figure i can buy one of each and try to swap parts and get a complete set and some leftover spare parts. Each set is complete with box and coin. What I'm curious about is what to pay for each set. I've only seen the parts and haven't talked price yet. Any input would be appreciated.
