As there are many counterfeits, some very well done and hard to differentiate from the real ones. Many coppers are found as much as 15
percent or more below the official weights, and even heavy specimens are occasionally observed.
I have a few coins of these, and some of them are off target as described above. But I was also wondering if it is possible to be a bit heavier, but not to be a counterfeit? As I will show in the pictures below..( sorry for my bad grammar, and possibly spelling
I have put 2x 20 Reis on top of eachother, as I noticed 1 was a little bit bigger / heavier (1827, coin on bottom).
20 Reis counterstamp on 1827 R, 40 Reis = 14,9 g. (which should weigh: 14,34 g., so how can it "grow" 0,6 g. ?
20 Reis counterstamp on 1828 R, 40 Reis = 13,02 g. (which should also weigh: 14,34 g. but ok, it can lose some weight due to wear etc.)
Also notice the bottom of the 1827 coin, it has been squeezed out or something ? Could this be PMD
or was it part of the minting proces?
As I don't see it on the other coins, although it seems they try to loose the date or does it have to do with the countermark?
Sorry for the ramblings
but I'm looking forward to hear some opinions, and if something is not clear enough... Just ask
