What is the value of 1940 5 Reichspenning German coin in good condition?

Answer 1

The word "Good" in numismatic jargon actually means "pretty heavily worn", so I assume you're using it in the general sense of "not a lot of wear".

Your coin's value depends on its mint mark. As of 12/2008 the most common variety with an A mint mark retails for about 75¢.

B or D, about $1.30

G, about $2.50.

Any other mint mark, about $2.25

Answer 2

In average condition, 50 to 75 cents.

With less wear it might sell for $2.50 - $4.00
