This one best coins I found metal detecting. A 35/50 ad celtic rose gold corrietivati volosis Dumnocoveros stater .
Wow! This is "One of" the best you've found? I'd be curious to see what others that you've found that are comparable I began collecting British-Celtic coins a few years ago, and it's been frustrating because examples show up very infrequently in auctions. Dumnocoveros wasn't on my "List to get" because of the rarity (price) and general lack of historical context (only know he even existed based on coins). But if I found that coin while metal detecting then I'd be over the moon!
