With all due respect, that's more than Jeff Bezos can say. I've realized over the years that people have an interest in precious metals and silver.
Silver is really the 'poor man's precious metal'.
It's affordable to most people. I've often given Silver Eagle coins as special gifts to loved ones. People always really get a kick out of them. The coins really are exquisitely crafted, and you don't see them very often. Then it occurred to me that millennium coins, dating from the last year of the 20th century and the first of the new millennium, would be a nice marketing concept.
