The "keystone" of my collection . . . . . post yours . . . .
A "keystone" to one's collection is a coin or medal at the top of the collection, one that given one's current and / or anticipated future economic condition, will probably never lose its status as the pinnacle piece.
Your keystone could due to its design elegance, its condition, its rarity, its price, or any combination of the former.
I've been able to acquire quite a few "nice" pieces over the past few years, but I don't feel that I ever captured a true keystone piece - until this week.
Here is my latest arrival and the keystone of my exonumia collection. It's a very rare 1805 medal by Friedrich Loos. It commemorates Dr. Franz Joseph Gall, the creator of the pseudo science of phrenology.
Only one has been certified by PCGS.
Let's see YOUR keystone.
