A couple of years ago I found that my dad had a mutual fund that wasn't listed in his estate. Funds were being held by the state of FL. Me and each of my siblings got around $1800 from that one.
I looked up my uncle's name in TN and found at least $600 due to my cousins... one item just says "securities" so I'll be interested to hear what that one is once they make a claim. Odd that it's unclaimed. One of my cousins lives at the old house and that's the address listed on the TN unclaimed property web site.

I'll be happy to send my address if you need to send me a finder's fee!
