Does anyone know how to tell km849 and km849a apart without using a scale? Both types were made in 1981.
Even with a scale, a difference of 0.02 grams is a very small difference.
Is there any difference at all in the way they look?
I have seen the pictures on the site, and the colour seem to differ. In real life, however, I cannot see any difference in colour. Bronze and brass looks quite similar.
If only the alloy changed and nothing else, is it only guesswork? Reasonably, every third should be bronze, and two thirds brass.
