After create the currency and denominations of Galleon https://en.numista.com/forum/topic153656.html there are these denominations without currency and unused:
53730 → 1 Galleon
53728 → 1 Galleon = 29 Sickle = 493 Knut
13279 → 1 Galleon = 29 Sickle = 493 Knut
13278 → 1 Sickle = 29 Knuts
Note: Is this type of request necessary, or does the Numista robot search for and remove denominations without currency and unused?
