Netherlands (KM #164; "KM" refers to the Standard Catalog of World Coins, by Chester L. Krause and Clifford Mishler) 25 Cents. 1939. Obv.: Bust w/narrow truncation (neck). 3.5750 g.; .640 silver; .0736 oz ASW; .0736 x $16.06 USD [current spot price of silver] = USD $1.22 (approx. bullion value as of 27 Sept. 2009). This coin is slightly larger than the diameter of a U.S. dime (dime: 17.9mm), and is approx. a gram more in weight. 4 million were struck (minted). Current retail values (USD) in particular grades are: Fine: $0.75; VF: $2.00; XF: $4.00; and Unc.: $8.00. Wholesale numismatic values are approx. 30% less. The coin in the image provided appears to be in Fine or Very Fine condition. Don't clean it! Cleaned, this coin would lose approx. 90% of its numismatic value (however, it would still be worth its weight in silver (bullion value). Addendum: Coin Prognosis: The numismatic and bullion value of this coin will probably increase in the short-term. Here's why: (1) Older coins of EU (European Union) nations in desirable grades (of condition) are becoming harder to find—most are being melted; (2) Mintage of 4m is low; many (or even most) of these 1939 coins have probably not survived to date; (3) Silver will probably increase in value in the short-term (looking forward 18 months). Personal note: As a dealer, I would not offer this coin for sale for less than $5.00 USD.
Great evaluation, thanks. I never clean a coin. Even as a kid I did not, not sure why, but I know it's a no no for sure.
