A difference in the weight of a coin

[realbluegold]

Today I received a '4 escudos de isabel II' gold coin from 1865.

I've weighted it and instead of weigthing 3,35 it weights 3,4 and I've recalibrated the scale 5 times. The other mesures are right. What do you think??? Is a 0,05 difference but I don't like it...

What about the measurements do they stack up with the specified dimensions.

 

EDIT: Is it badly worn!!

im not a gold expert  but is that a really big deal , sureley someone wouldnt fake that coin would they isnt there a leeway on weight + or -

i was led to believe all silver coins are different weights  

just my thoughts

You need to check the diameter to see if it is around 18mm. 

 

The actual weight is supposed to be 3.3548g. Are your scales to two decimal points or three? If it is two, then your scales could easily round it up to 3.4g. If the scales are to 3 places then I'd be interested to see what they say.

the diammeter is close to 18mm. The scale has two .two decimals...

does it say 3.40 g ?

[HighlandTiger]

If the diameter is 18mm I would not worry, 3.4g is only 1% over weight. There are no other metals that could get any where near that weight for that diameter of coin.

 

Don't worry, it's a genuine coin.

With fake gold coins the diameters are typically / always correct.

It is the thickness that is incorrect.

Fakes tend to be underweight but definitely too thick.
