Sean W. writes: I have a copper coin approx 24mm in diameter with a 5mm hole in the centre. It has the inscription NEDERLANDSCH INDIE 1937 on one side and a 1 C with a mark resembling a plus sign in the C. The other side has an inscription in Indian or Arabic.
The Netherlands East Indies (The Republic of Indonesia after 1942) was under Dutch rule from 1816-1942. The 1937 1 cent (100 cents=Gulden) was minted in large quantities, about 120,400,000 pieces were struck, at the Utrecht Mint in the Netherlands. The coin features a flan with a center hole, a device that allowed the coins to be stored on a “counting stick”. Only the 5c coin in this period shares this feature.
Values are modest due to the large number of pieces available in the numismatic market. Approximate value range: US 10 cents – $2. (uncirculated).
