Here's my thoughts on this intetesting domain which has sparked much debate
I'm thinking that it will likely not be picked up by any of the major brandables marketplaces because of the possible negative connotation / confusion with micro spores type of mould.... I know that it is the other kind, but they are super careful about potential confusion and negative connotation.
Looking at search volume (480/pm) and CPC (34c)... once can see that there is a market for this product, however it is a VERY small one... and while most domainers prefer higher figures, there might be a tiny niche that might in fact purchase if you're very lucky.
For further context... There are less than 340 pages on the entire internet that even attempt slightly to rank for the term... this shows VERY little interest commercially. For reference, the very specialist term "aged domain" has almost 3,000 pages devoted to it.
The "coin mould" term is also very narrow, with only a tiny amount of possible uses for the domain.
My valuation would therefore be as follows:
If you are lucky enough to find a buyer at all.... here's what I think you can most likely expect:
From a serious end-user as high as $300 if you're EXTREMELY lucky
From a curious end-user as high as $140 if you're lucky
From an investor with a buyer as high as $70 if you're lucky
From an investor with high hopes as high as $35 if you're lucky
From an auction on Flippa, Sedo, Godaddy, etc. as high as $25 if you're lucky
From an auction here on Namepros as high as $15 if you're lucky
Looking at previous similar historical sales it certainly validates my initial valuation:
