The most practical two dollars ever kept on a keychain. The Trolley Coin Keychain is the ingenious little accessory that solves a very specific, very common frustration — never having the right coin for a supermarket or carpark trolley. The detachable coin (24.8mm diameter, 2.7mm thick) is always exactly where it needs to be: on the key ring.

The coin detaches with a simple press, slides into the trolley slot, and reattaches to the keychain when done. Durable metal construction built for daily use over years. Compact enough to add minimal bulk to any key set.
