South Korea (KOMSCO) exonumia bullion missing proof and size variants

Hi,
I'm new, but would like to help add some entries for South Korea's (KOMSCO) exonumia bullion missing proof and size variants. I started by trying to see how I can add a proof nested in with the BU versions (as that is how I see the years which do have both), but I'm a bit lost where to add it when I follow the add info link. I also don't know what I can use as documentation for some of these, aside from the fact I have some, and others I know are found listed in NGC's graded set lists (and some only having shown on ebay). KOMSCO's website I haven't found useful for catalog details, tho maybe I'm missing where it is on there.

there is a proof version with a mintage of 500

There are some notable interesting ones not listed at all, like the Chiwoo Cheonwang 2018 incuse silver 2 oz version; the Tiger 2018 silver 10 oz BU, which features a different image than 1oz BU silver; and the ZI:SIN Canis 10 oz in BU and Antique Finish (though, frankly, it's possible the antiqued was done afterward by another party than the mint).

I'm sure there are many I'm unaware of, but I'm interested in helping get some of this and more added, if I could get some assistance.

thanks

​Hello and welcome to Numista!

Maybe start off with a relatively easy one, modifying an existing page, to get a feel for how it works. Click the Modify or add data on this page link at the bottom (or the icon at the top right). That will open the modification page. Under the BU mintage year line add the new proof (I'm assuming it's 2020 KOMSCO 500 with comment PROOF). Then add your evidence that this really does exist in the Sources box. After you hit the Modify data link it will go to a referee for validation (usually takes from hours to weeks depending) and will appear in your Modification requests with a status. Creating a new page is somewhat harder. If you haven't found this yet, you should read it.
