You can’t take it with you…

…but you could have quite a bit of it left on your tombstone. Money, money, money, change that is, being left at burial sites. I have seen this done with clarity as to each coin representing something and then I have seen families that just leave change. It can be any and all denominations with really no meaning behind it except that they visited the grave. It is nice to know that someone other than yourself has visited the grave and remembered your loved one.
