Greenland currently uses the Danish Krone, why isn't it shown when you hover on the map? [Risolto]

The Danish Krone coins have been circulating in Greenland since the Krone was created in 19th century.

Why isn't it shown when you hover the mouse on the map?

I'm guessing it's for the same reason as Puerto Rico, Saint Pierre and Miquelon, and a few other locations that use their home country's currency but at one point used to have their own money.
Don't ask me what this reason is, though - I'm not sure either. It certainly isn't 100% consistent (Azores, French Guiana, Newfoundland... and those African places in the unions, for that matter).

That said, Greenland is, in fact, fairly autonomous, so it does make a little bit of sense to count it independently. (And it's a nice gotcha for those OCD guys who want to color in every point on the map. Though Liechtenstein is harder anyway.)

Then, for the sake of consistency, we should remove the German coins from Poland's map.

Or add the coins to the territories... I think personally that Russia-Empire shouldn´t be limited to present Russia only, but to the same extent as the USSR...

If French coins count for Guadeloupe and Reunion, than Danish coins should count for Greenland.

For consistency, French coins should not count for Guadeloupe, Reunion and French Guiana.​

​As they indeed do not for Saint Pierre and Miquelon. The current map is anything but consistent; not sure why.

Officaly then the Dutch guilders from 1949 to 1962 also were legal tender in Dutch new Guinea , (so the left part of New Guinea which now is Indonesia)

TL/DR: the map is a ridiculous simplification, and should really have proper historical borders.
Unfortunately, in most cases, coins of the same "country" (even if they belong to the same currency, or, in some exceptional cases, even to the exact same type) made at different times had very different circulation areas (and in some pre-modern cases, we might not even be sure about what those were), which makes it pretty much impossible to apply everything properly (at least, as long as we're trying to base it on "country" counts - and that's including the planned new system, because it is hardly going to distinguish between, say, pre-1962 and post-1962 guilders, especially since they have the same Numista page).

That said, the whole "technically legal tender in" thing can be rather silly. IIRC, US coins are still technically legal tender in Ecuador - would you color in Ecuador for US coins?
