Oh no! Your coin is holed? I'm sorry to read that! That makes it worthless. Collectors will only very rarely buy holed coins as fillers for their collections when the coins are extremely scarce, and at highly reduced prices.
These coins, however, are not scarce. They are borderline modern coins minted in copper-nickel with quite high mintages and a quite low demand.
These are approximate catalog values for the 1940 10 and 25 aurar coins from Iceland.
worn: less than $1 approximate catalog value
average circulated: less than $1
well preserved: $1
fully uncirculated: $3
The 10 aurar coin is slightly less common than the 25 aurar coin in fully uncirculated condition where it catalogs for $5.
