Just a thought, but could the Faroese Krona which is exhcanged 1:1 with the Danish Krona get the exchangerate shown on Numista? I'm thinking mostly of the banknotes, since those are the only, which are used at the moment.
I have a soft spot for origami paper cranes.
Read or watch about "Sadako Sasaki and the Thousand Paper Cranes".
Spread a little peace and happiness wherever you go :)
The Faeroese Krona is NOT regarded as an independent currency, but a local version of the Danish Krone, as was the Greenlandic Krone.
This is in contrast to the currencies in eSwatini, Lesotho, & Namibia - which are all independent currencies, but pegged 1:1 with the Rand, which also circulates in these 3 countries as well as in both South Africa & Zimbabwe.
