ASE's.... Is it just me?

[HighlandTiger]

I always weigh my coins when they arrive just to check and I've noticed that all my American Eagles are always well overweight. 

 

Supposedly they are meant to be 31.1 g the same as every other .999 1 oz coin, but I regularly get ASE's that are as much as 31.6g. Now I don't mind getting a tad extra silver, but has anyone else noticed this?

Yes i have had A.S.E'S at those weights,they pass the magnet test and have the cartwheel affect.on close inspection along side another A.S.E they look the same.Also they came from a reputable dealer.Oh and they have milk spots too.

You are guaranteed to get 1 troy ounce of silver. Remember that 999 is very close to pure, but it's not completely pure. Add to that the tolerances on manufacture, and there will always be a little more metal than the minimum spec.

Explains why they've always felt really solid to me. Cartwheel effect?

Simple technique but weird to describe, this video shows what is meant by it quite well. It's a simple method in our box of tricks to detect fakes.

No. 999 is classes as pure silver. The coin does not have to weight 0.1% more to be classes as a full Troy ounce. At 999 it can weigh exactly 1 Troy ounce because 999 is classes as pure silver.

I noticed that to and Libertads are sometimes just a little bit under 31,1 gr.

[Danny-boy]

I thought .999 was fine silver and pure silver was actually pure.

But you are right CS, 999 is classed as pure silver.

[silversword]

It might well be "classed as" but it cannot actually be pure at 99.9% - otherwise it would be 100% 

[ChrisSilver]

If going but that definition of pure then nothing will be pure unless you produce and keep it in a complete vacuum.
