I hope the finder and the owner get to keep a relic apiece as an heirloom. I think I’d have made sure to pocket one before turning in the hoard.
There was a metal-detector find a few years ago I read about in England that was moderately-sized, and the owner somehow was permitted to keep or bid on (and win) 1 small piece he liked. I cannot imagine that some accomodation will not be reached with these 2 guys if they are interested in keeping an item, which one would think they might certainly be.
