I doubt that, can you show a pic of the coin? I think 0.10 grams is nothing and would likely come down the accuracy of the scales.
11.31 g , at times some year maybe slightly. you need to check your scale, accuracy maybe out. This type of coin they are pretty spot on for weight, size. maybe fake? please use magnet
That weight sounds a bit off. I have a florin in my collection that weighs around 12 grams, so 11.41 grams might indicate it’s a fake or tampered with. I’d suggest taking it to a coin expert to get a proper evaluation.
At Alikai Following on from 1Tim58> I have 4 sets of scales and they all weigh minutely different values.Nothing in a monetary sense as we are talking about 'cents' difference but unless one has more expensive calibrated scientific scales that are definitive I would allow for the margin of error in pocket scales (Assumed to be) 06/07/2024
