Will post proper pictures later on tonight when I get a proper camera. As you can see my mobile photos are too blurry to see anything from. I was just throwing the question out there to see if any information out there about this coin was common knowledge   |

There was a 2010 fine silver set but they were all minted in proof finish. Even from the very blurry pictures it doesn't seem like yours is a proof coin. It might just be circuleted in which case better pictures will help. Is it thinner than a normal $2? it might be a different planchet. I think the most likely thing is that someone has plated it with a silver metal.

The true silver version of the coin would weigh 8.55g rather than the usual 6.60g for the circulating version. Looking forward to some better photos...  |

Its not a proof finish so its not out of the masterpieces set. Most likely plated I think.

I would guess nickel plated.
Have a very close look over the entire coin with a powerful jeweler's loupe.
If it was suspended in a plating solution, the contact points from where it was suspended may show up unplated.

You know how you often see coins on ebay (mostly 50c pieces) gold plated? Maybe someone was thinking of silver plating to cash in on people's stupidity and start silver plating the gold coins and when they realised was dud idea threw em into the wild. |

Our current silver coins (Cupronickel: 75% copper & 25% nickel) being the 5c, 10c, 20c & 50c will turn a golden colour if cooked in the oven.
Our current gold coins (92% copper, 6% aluminium & 2% nickel) being the $1 & $2 will turn a purplish colour.
That's our science experiment for the evening. Use a few of the same denomination, maybe one wrapped in aluminium foil, maybe one wrapped in baking paper & another wrapped in something else that's not burnable. Set oven to a lower temperature, maybe 150ยบ for a decent amount of time. See what changing the temperature & times will do to alter the colours.
