10 Dollars Me 262A-1a Schwalbe

The Me 262, the world's first operational jet-powered fighter, entered Luftwaffe service in 1944 after Hitler's insistence on configuring early production models as bombers delayed deployment by critical months — a decision that almost certainly cost Germany its only realistic chance of air superiority in the final war years. The A-1a designation denotes the pure interceptor variant, armed with four 30mm MK 108 cannons.

The Marshall Islands issued commemorative brass dollars throughout the 1990s at a pace that flooded the novelty market, and most examples remain in essentially uncirculated condition simply because they never functioned as currency.
