The six-coin set has to be entered one coin at a time. It is members who
create the pages on here, so if no page currently exists then no member has that coin.
There is the $1 page ...

so the other five pages need creating - which you can do if you want.

​Okie. Thank you.

I also have a suggestion. Is it possible to group those proof set into 1 group? When I see the lines of years, I am going crazy. You have example 1984 with mint mark 1984 without mint mark. Instead I feel it is better to group those with mint mark as 1 group and those without mint mark as another group in the same page.
