The weight is a little high. Time to buy a cheap test kit, or take it to a pawn shop and have them test it.

I don't understand... I scratch it, underneath it's brown...then I scratch more, it's silver  . I think I'll have to commit the ultimate numismatic sin and ask my dad to drill into it to see what's really underneath (though I don't really care, it's a 3$ coin. If it's silver, then I don't care because it's still a profit)..sorry coin  |

Do you guys think it's silver or very heavily plated copper? (Please don't shout or scold at me guys, I just wanted to know quickly and I know what I did was wrong even though it's bullion)  |

Why is there copper in random places? I see all silver where you drilled, and copper around it.

I know, that's why I had to drill. I did a little scratch at first and I just saw copper so I had to drill to find out if it's silver. Maybe a small plate of copper inside and the rest is silver (it has the good weight and is not magnetic).

Copper is a bonding agent for chrome and other metals. Based on the layers, I wouldn't be surprised if this had some sort of base metal for its core, then flashed with copper, then chromed. But, truth be told, it really doesn't looked chromed. I agree with the above, cheap test kit will help a lot, now and in the future. |

My vote is copper was used as a bonding layer for silver.

harrison2, do you know what base metals it could be for it to have the same weight as the silver coins and be non-magnetic?

Did silver test on plated area, turns creamy-blue/green and I wipe it off and it is creamy and the contour is coppery red (either the plate burnt away or it's the remnant of the acid). Test on drilled bit, stays the colour of testing acid (yellow) and wipe it off, it is black. My acid is JSP and I don't have the colour charts.

Before performing destructive tests, you should have checked the Specific Gravity. SP would be definitive but your drilling has introduced more questions than answers.

Looks like a brass plug plated with copper as a bonding agent and then plated with cadmium? or some shiny metal. The copper layer is a dead giveaway.
