The Dinosauria Collection: Behind The Design

Elementary school kids will love these coins.

Unfortunately, with lots of 'bright 'n shiny' silver proof issues from all major Mints around the World,
when it comes to selling them, low buy back prices have to be expected.
They are best bought with the idea and intention of always keeping them, with no intention of ever selling them into the secondary collector market some years later.

My local LCS in most cases, won't offer to buy them for much more than the actual silver bullion value.

There are one or two exceptions,
but they usually involve extremely low mintages, of very high significance to the collector, and where the Mints originally offered them at very high prices to justify the low mintages. (Otherwise, no profit for the Mint that issued them.)
