Hi
There are multiple sites of colored Euro coins on Numista, which in same original non-colored issue are used as a currency in Eurozone (I am sure that pretty much everyone would accept colored coins as a mean of payment). I am only listing pieces with same denominations as being in circulation. The question does not apply on flood of other fantasy denominations made solely for profit.
Here are some pieces:
N#78890 (same KM as https://en.numista.com/catalogue/pieces76635.html?? - other similar cases is this cool with everyone?)
So if I get this right, if Euro coin is colored by the officially approved mint for same Euro coins, they can color the coins all they like and Numista accepts these pieces, but at the same time does not accept pieces, which are colored by mint, which did not mint the coin itself? Like for instance colored Finnish 2 Euro “10 Years of Euro Cash” coin, probably colored by Bavarian mint. I would just like to know if we can expect some additional deviations from Numista rules in future?

Thank you
