Finland mint weight accuracy - 10 Euro silver Proof

[Lupo902]

Good morning,

I recently purchased some 10 Euro proof silver coins from 2003 Finland, commemorating the 200th Anniversary of the death of Anders Chydenius, with box and certificate.

The weight declared by the mint and on the certificate of authenticity is 27.4 grams, in reality when I weigh them I get values from 26.88 grams to 26.95 grams. Do you think this weight difference of around 2% could be normal?

Thank you

I have a wight discrepancy issue too with the Perth Mint.

I have one Perth Mint 1992 (1 oz KOOKABURRA) silver coin with an odd weight of 32.2 grams! I emailed the Perth Mint questioning this odd weight for one ounce of silver, and they told me that it's possible since they did not have precise equipment back in 1992!🙄

I had a similar question about some 2016s that I fully believed to be genuine.

They said that as long as they were a little overweight (never under) that is within 'tolerance' for silver coins.

Of course it's a different story for gold, that should always be spot on (no pun intended)

Have you calibrated your scales?

I see reports like this from time to time and the common denominator is that involve proof coins.  Do government mints just not pay attention to QA/QC when making them?  Back in 2012, the South African Mint acknowledged their proof Krugerrands were out of spec:
