I have a 1652 new England shilling it weighs about 7.9 grams a few mm larger than a U.S. quarter, non magnetic and it's a tarnished silver color. It's very worn down. i would like to know any information if it is real/fake or should i take it to a collector for further investigation
Hard to tell from those pics, but I agree with the previous posters that something doesn't look quite right to me.
Another major Red Flag - the planchet is almost perfectly round and the strike is almost perfectly centered. That almost never happened on genuine specimens. The pebbly surface certainly points to a cast fake. Here's a test... balance it on your fingertip and gently strike the edge with another coin. Struck coins ring; cast coins emit a dull thud. Obviously, do this such that if the coin falls off your finger it won't roll of the table onto the floor. One way to do that is to have a soft towel on the table.
