Seems to be a great idea. The timing appears very good. It is and will be a highly appreciating asset. Price of silver alone, should go up and up and up.
Let's ask the MintMan; can't you use the same dies to create 100 proof rounds and then 1,000 BUs? Most people will want BUs due to financial restraints but for various reasons, the proof rounds are popular among collectors and they tend to appreciate a great deal more in price.
Yes! Should be able to use the same die, which is great news! Working with Phelimint to figure out some of the details!
Unfortunately you cannot use the same dies, the proof dies are highly polished and slightly different.
