This is my first offering, and may well not count but I'll have a go.
1 butut from The Gambia featuring a peanut. The reason this may be disqualified is because the same design was also featured on the colonial 6 pence (KM#3). However, I think that as a continuation of the design from colonial rule through to independence I might be allowed it. Unless, of course, there are other peanuts out there. I would also ask that coins featuring characters created by Charles M Schulz, if there are any, are not counted as the same.
