I just came across the same issue reported by Darioelle, and I agree it needs attention.
There seems to be a lot of confusion about this coin.
First, the fact that both lines in the valuation table are marked as “proof”. The SCWC does not mark the 600,000 mintage line as “proof”, only the unmarked restrike line (with an unlisted mintage). So, it is tempting to just edit the page to remove “proof” from the line with the 600,000 mintage, but -
1. The majority of Numista members who own this coin claim to have the unmarked proof restrike, not the original 600,000 mintage version (which seems unlikely).
2. Grades are given in the valuation table for both versions of the coin (which Numista considers to be proofs). The unmarked restrike proof (which is a newer issue) has grades down to “F” (along with values) which I find very odd. The line with the 600,000 mintage (presumably the original circulating commemorative coin - not a proof - has conditions listed only down to "VF". I am not sure if I have ever seen a valuation table on a Numista page that gives values for heavily worn “proof” coins (except for this one).
3. Based upon (1) and (2) above, it is likely that many people have been entering the circulating commemorative version of this coin on the “proof restrike unmarked” line for some reason, so removing the “proof” comment from the line with the 600,000 mintage figure would not fix that.
I suggest that what needs to happen here is for the administrator of the site to completely re-do the valuation table for this coin (wiping out all existing data in the table). The new table would then have the 600,000 mintage coin being the original (non-proof) issue. Everyone who has indicated ownership of this coin would then be contacted and asked to re-enter their coin on the appropriate line in the table. I also suggest some pictures be put on this page to clearly show the difference between the proof and the non-proof versions. Photos from the auction results on the page could be used; for example, auction 182/lot 1737 and auction 171/lot 1577 appear to be the circulating (non-proof) version, and premium auction 175/lot 74 appears to be the proof version with mirror fields and frosted details.
