Everyone Chime in:Advice

Hello All, 

I seen this on reddit  guy had doubts about it, and took it to his lcs that he bought from who sigma tested it and said it is real.

Do you think it is real?

Never seen silver like that. Perhaps chemical corrosion? If it is real, imagine how difficult it would be to sell it.

Looks like the acid had lifted the silver plate from the base metal.

From the photo blown up, that is silver plated.

[HillWalkerDundee]

Silver plate, agreed

There is a possibility that it is a de-lamination ,where the bar  used to make the original Planchet, had foreign matter within it.

When this is then rolled to make the silver sheet for the rounds, the foreign matter is elongated with the pressure of the rollers, so will form a strip or voids across the planchets.

Once the dies strike the blanks the gases trapped in the dross , blows out the debris through the thin silver layer.    

Or it could be a Chinese Friday afternoon special.

I was convinced it was plated but that alternate explanation is interesting...

From an engineering point of view it looks plated to me.

Would love to be able to cut this along both axis to see what the actual make up is,

I would not do this to any coin of any value, and this in itself is probably valuable to a error collector, however it is more bullion than numismatic,so most like a melt coin anyway(if not a plated copy)

There is probably a few of these given the flaw runs across the whole surface. 

 I would have thought a plated ,however Sigma testing found it to be pure, so to me it is more than likely a de-lam albeit a very severe one.

  @MintageSellerthis looks similar if not as extreme, and is a de-lam
