Extremely pristine and authentic old red copper ingot. Weight: approx. 920 g
Length: approx. 21 cm Width: approx. 2.5 cm
Height: approx. 2.5 cm
On one side the numbers 75 & 4 are caved into it.
Possibly these were used as currency or to trade?
This authentic red copper is already more than 45 years in my possession and has never been treated in any way, which makes that all patina is completely in the original condition.
Some old carvings are visible: possibly with the intention to check on the material (red copper).
Have a look at the pictures for the many details to give you a good impression.
