Super! Thanks a lot

This is the search I did (in the Coins tab above) using the known 50 and 1971 ...

and your coin is in the results.

That's true :-) good tip for future searches!

​It certainly is, but it still has 149 possible hits. If you click on "+ Add filters" in the search and you put 1971 in the year box and 50 in the face value box, you can narrow your search down from 149 to 68. Of course it's a little bit more effort but you regain that by narrowing down the search: https://en.numista.com/catalogue/index.php?r=&ct=coin&tb=y&tc=y&tn=y&tp=y&tt=y&cat=y&ru=&ca=3&no=&v=50&d=&i=&a=1971&dg=&m=&f=&t=&w=&u=&g=&se=&c=&wi=&sw=

​And if you use the other easily known attribute, diameter = 18 mm you get exactly 1 hit. What could be easier?
