A coin made with Tank Encyclopedia, the first online tank museum, for everyone who has ever fallen down a rabbit hole of odd armour.

TOG II was built by William Foster & Co. of Lincoln in 1941, the same firm behind the first tanks of 1916, for a war its designers expected to look like the last one. Eighty tons, one built, and it never went to war. Its nickname comes from the committee behind it: The Old Gang.

How it works: reserve your coin for $1. If 100 are reserved by the deadline, we charge the rest of the $25 price plus $5 shipping worldwide. If we don't reach 100, your $1 comes back. The first 100 get a free leather case and a numbered card.

Front: TOG II in relief, with TOG II below. Back: the Tank Encyclopedia track-link emblem, with TANK ENCYCLOPEDIA above and THE OLD GANG below.

Spec: 45 mm, die-struck brass, antique finish, in a clear capsule.
