This coin has been originally entered incorrectly > https://en.numista.com/catalogue/pieces179736.html
It was issued in 1993 as a Proof coin as part of a set and then in 1994 as an UNC Bullion coin by itself. I have added the correct mintage lines for those years.
The entry for this coin on Numista has a 1990 mintage line which is incorrect and a 1995 Mintage line which is also incorrect. This coin design was not issued in those years.
One member is listed against each of the incorrect mintage lines.
Please move the members entry on the 1990 line on the above coin to the 1990 line on this coin >>>> https://en.numista.com/catalogue/pieces237767.html
Please move the members entry on the 1995 line on the above coin to the 1995 line on this coin >>>> https://en.numista.com/catalogue/pieces237824.html
Once the members entries have been moved to the correct coins the 1990 and 1995 mintage lines on coin number 179736 can be deleted.
I hope this is able to be understood. These Koala Platinum coins are a complicated set of coins and there are a few missing which I am going to sort out.
