I have a set of three Australian $5 silver, gold and platinum coins in a decorative box. I found two of them, but can't find the third in the Numista catalogue, so I can't add it to my collection. I've tried searching for a few different terms, but with no results. The closest I've found is a $5 coin that is identical to mine, except it has a red kangaroo that is jumping, instead of the grey kangaroo standing still (https://en.numista.com/catalogue/pieces112949.html) I think you can see all the necessary information on the pictures, except that it's 14 mm in diameter and that I bought it at an auction held by a coin collectors club I belong to. Is it actually possible that I have a coin that isn't in the catalogue or, more likely, am I not using the right search terms?
