Trolley Token

Simple double ended trolley token in three denominations £ coin US quarter Dollar and One Euro.I have only checked the £ version, the others sized from Dimensions on the internet.The pound one works fine tried at Tesco, M&S local garden centre. The others I haven't tried for the obvious reason.
I thought the double ended idea would give a sensible grip area and as it was plastic actually double the life of the token as you can use it both ways. I never put a key ring hole in it as I didn't think it would be such a good Idea to have your keys hanging on the trolley, better to keep it in your pocket or purse.
Added the new Pound coin in two forms, the double ended and a new single, as I found the double ended didn't work on all trolleys.
