These are really pricey if you can find them at all. But I can not see these going down in price, ever. There will probably come a day when the LDS church wants these and they do have deep pockets. Anyone have any insighs or stories about these.
The church already owns a boatload of 'em - doubt they'd want any more. You can find out just about anything you want to know Right Here - just scroll down
There are reference books available as well. I have "Mormon and Utah Coin and Currency" by Alvin E. Rust, 1984. These are frequently available on ebay (where I bought mine). 247 pages, over 300 pictures.
