It's hard to miss the big number 10 on these Swedish ores. These coins are all minted in silver:
10 ORE: 0.019 troy ounces silver
Silver coins can never be worth less than the silver they contain. If silver were trading at, say, $20 US dollars per ounce, a 10 ore would be worth at least Base Value (BV) of 0.019 x 20 = 40 US cents. Look up the price of silver. It changes every day.
Coins in good condition, with good collector appeal, are worth more than base value, as follows:
10 ORE 1909 TO 1916
worn: BV + $1
average circulated: $2
well preserved: $10
fully uncirculated: $40
10 ORE 1917 TO 1942
average circulated: $1
well preserved: $2
fully uncirculated: $10
The values above are general values for the dates shown. If you get a coin catalog, you will find that there are a few special coins which have special characteristics, and are worth more. For instance, a 1936G with a 'short 6' catalogs at $20 in well preserved condition. Such varieties are beyond the scope of our CoinQuest forum.
