Oldest Silver Dollar?

[jadedreams]

Hey guys I was just curious what is the oldest silver dollar you've had or heard of? Most sites say 10+ years, I've seen several reports of them 15-20 years old though.

I've got a big 6-7" dollar that came with a 125 tank I bought about 5 years ago. The guy I got it from said the silver dollar was 13 years old then. I also have 3 other dollars that are about 7-8 years old.

There was a school of 6 in my father's tank that he set up roughly 17 years ago. There are two males still alive, healthy and as stupid as ever. When this year is up that'll be about 18 years for them.
They're about the same size as the one you mentioned... roughly 7".

There is a 27 year old on YouTube... Don't know how accurate that is.

I have some that are 7years and still look and act young. They are the wide bar Schomburkii type.
