Solomon Islands Pizza $5 Silver Crown. £34.50 (FSO8101)
Firstly, it is not made of pizza but of 999 fine Silver and was issued by the Solomon Islands in the South Pacific. It weighs 20 grams, is a $5.00 coin with Queen Elizabeth II on the obverse and the mintage is a very small 1,500 coins and it was issued in 2015.
What they have done is printed a full-colour picture of a pizza on it and impregnated the smell of pizza in the picture. They guarantee approximately 60 rubbings per coin for you to smell the pizza. The box it comes in even looks like a pizza box, in red, white and green, the colours of Italy. Everyone who has seen it loves them, once they get over the disbelief that it actually smells of cooked pizza dough, fresh herbs and melted cheese.
