If there are any collectors or hoarders here, Please heed this warning.
Eventually you won't be around to take care of your collection. It will eventually be passed down to someone who doesn't want it, and wants to get rid of it.
My dad is a hoarder. There is tons of junk, but there are a few gems mixed in. The problem is, once I inherit it, I have no idea what's actually valuable because it's mixed in with a lot of junk. I cannot research each individual item.
If something is not clearly labeled as valuable, or on a list of valuable items, then it will be lost forever. In my case, my dad has actual junk and trash, I will be renting a dumpster, and something that someone else might want to collect and be willing to pay a high price for, will inevitably get thrown away and lost for good.
If you are a collector or hoarder, and you care about your items, make sure the most valuable ones are identifiable by whomever inherits it.
(I will try to reach out to other collectors before getting rid off stuff, but there is so much junk, they might miss things as well.)
