A keyring holder to hold a £1 pound / trolley / locker token that will fit a KeySmart keyring. Tons of these around, but thought it a good exercise to design one myself
I haven't tried it for a Euro or US coins. If you have any of these coins and it fits let me know and I can update the description.
It's a little stiff to push/pull the coin out, but as the edges of a £1 are rough it should loosen up over time. Plus I don't want to lose my £1 so for me it's a choice between loose and lose my coin or tight and keep my money.
