These coins were minted in aluminum bronze, and the picture shows an uncirculated specimen. Isn't it something?
In fully uncirculated condition a collector would probably pay in excess of $20 US dollars for a common date 5 rentenpfennig. In general, catalog values run like this:
5 RENTENPFENNIG AND % REICHSPFENNIG (COMMON COINS)
worn: $1 US dollar approximate catalog value
average circulated: $3
well preserved: $10
fully uncirculated: $30
Like most coins in these two series, requester PAJ's 1924A is a common date and mint mark. The valuable dates and mint marks are:
1923A: $4 US dollars approximate catalog value
1925F: too rare to estimate value
1925F: $16 (Must have a large F mintmark, not a small (but still capital) F)
These are catalog values for average circulated coins. Use our Important Terminology link to convert from catalog value to actual value.
The catalog says there is one known example of a 1925F 5 rentenpfennig. If you've got it, congratulations! There are 20 million 1925F reichspfennigs.
