1 oz Silver Holiday Medallions

Hello, I collect the dated christmas/holiday silver medallions for my
daughter. These are 1oz .999 silver coins, with a holiday emblem on the
stamped front (tree, snowman, elf, etc), then stamped with the year on the
back. Usually, you can inscribe something on the back as well, although I
never do. Does anyone know where I could get back years of these type of
medallions? Somehow, somewhere, I've lost the 2000 medallion. Thanks so
much if anyone can help. I'd like to ensure that my daughters collection is
complete. I also did not buy one in 2002, but can still find those I would
imagine.
