That eagle looks like he means business!
These 1 groschen coins are made of bronze and bring low values except for the 1931 coin which is the 'key' date. Here are some approximate catalog values:
1 GROSCHEN EXCEPT 1931
worn: less than $1 US dollar approximate catalog value
average circulated: less than $1
well preserved: $2
fully uncirculated: $5
Groschens dated 1938 are a tad more rare; double these values for that date
1 GROSCHEN DATED 1931
worn: $10 US dollar approximate catalog value
average circulated: $20
well preserved: $35
fully uncirculated: $70
As always on CoinQuest, the values above are catalog values. They must be adjusted to obtain actual buy and sell values. Go to our Terminology page for an explanation about making these adjustments.
