https://forums.collectors.com/discussion/1115817/2-kopeks-1963-magnetic-transitional-error-weight-1-78g-unusual-color-die-defect#latest
For this 1968 coin:
Weight: 2.05 g
Diameter: 18.10 mm
Strongly magnetic – attracts to a magnet without even touching it
Alloy color is much lighter than other brass 2 Kopeks from the same year, possibly indicating a higher iron content
Comparison photo included – the magnetic coin is on the right.
🔍 Questions for experts:
Could this be an alloy variation or minting error?
Have you encountered other magnetic 2 Kopeks 1968 before?
Any estimated value range for such a coin?
