After asking this question for many months on tnet, I have to give you this answer. It all depends on what you want to do, not what others think you should do. Many people tell me gold is at the highest price its ever been in 10 years! I say, even though I find gold jewelry sometimes, I would like to look at it again one day. The reason why is to unlock happy memories of me spending time hunting with my hunting buddy and finding the item. If I sell it, then I will waste the money on something stupid like action figures or comics.
If I keep it, I get to look at it forever. The only time I would ever sell the gold was if I was going to get enough to buy a really nice silver coin or copper large cent that I needed. Or some key date wheatie. Other than that, just keep it as a keepsake thing.
