You've got a 10 ore coin, Tanya, and my picture is of a 25 ore. Both look almost identical except, of course, for the big '10' or big '25' on the reverse side. The hole in the middle makes them hard to miss.
These coins were made of copper nickel until 1941. Then there were several years of zinc minting. Copper nickel returned in 1946. In general, the zinc coins are worth about one-half as much as the copper nickel coins.
Here is what coin catalogs say about Denmark 10 and 25 ore coins from this era:
worn: $1 US dollar approximate catalog vaule
average circulated: $2
well preserved: $10
fully uncirculated: $20
worn: $2 US dollars approximate catalog value
average circulated: $5
well preserved: $20
fully uncirculated: $40
Be sure you understand what catalog value means by looking it up on our Important Terminology page.
The figures above apply to most dates. There are some special dates which are worth more. The list below gives catalog values of the special dates in average circulated condition:
1933: $10 (your coin, Tanya!)
1945: $40 (zinc)
1947: $150 (copper nickel)
1940: $2 (these are very common and worth only a little)
1946: same as 1940
