I have a Dutch 1 cent from 1942. It is not KM170, the zinc 1c issued during occupation. My coin is certainly the bronze KM152 version, very similar to the 1941 issue.
If this coin doesn't say "Curacao" on it, and is identical in design to the Netherlands KM152, why isn't this coin listed in WC as such? Why is this coin credited to Curacao when there is no marking on the coin as such?
This is even more frustrating since there IS a 1c from Curacao dated 1944 that says "Munt Van Curacao" on it.
Not sure if it would answer your question, but here is what I found out ...
There are some coins issued with the name of Netherlands Antilles (there are 27 on Numista) on them. Even though they are in the Caribbean, a long way from the Netherlands, they are a part of that country. It is a group of five islands - Curaçao, Sint Maarten, Bonaire, Saba, Saint Eustatius.
When Germany occupied the Netherlands in 1940 the link of the Netherlands Antillean currency to the Dutch currency was broken. So the U.S.A. minted coins for the islands - with D or P mintmarks - and they issued 1 Cents of bronze in 1942, 2½ Cents of bronze in 1944, 5 Cents of cupro-nickel in 1943, 1 Guilder of silver in 1944, 2½ Guilder of silver in 1944.
So it is probably the small P mintmark and the 1942 date that makes it from Curaçao (as the otherwise identical Netherlands 1 cent was issued from 1913 to 1941).
much the same as the 1941 faeroe islands coins which were minted by the royal mint without the heart mark on the obverse. they were issued because the mother country of denmark was occupied by the nazi's
