I have been updating this coin page with correct mintages and missing descriptions etc ....
https://en.numista.com/catalogue/pieces1003.html
I found that there were two different entries for the 1966 Proof set
41 Members have their coins listed against 1 mintage line for the 1966 Proof set
24 Members have their coins listed against the other mintage line for the 1966 Proof Set
The RAM only issued one proof set in 1966, all minted in Canberra. A total of 18,054 sets were produced.
Can an Admin member please move the members coins that are against the "Proof Set - To be moved" mintage line into the "Proof Open Year Set" mintage line?
This will correct this mistake.
Thankyou - Mike
