I would agree with you on silver dollars and bullion, but the value of silver dimes is about $1.75 a piece. So I have never heard of them being faked- not enough juice in the squeeze.
Maybe not dimes, but silver halves and quarters are being counterfeited. There are plenty of articles about fake junk silver. Just ordinary dates, nothing at all numismatic. If they haven’t gotten to dimes yet, rest assured, they will. Yes, it is a true truth that a dime seems too small to counterfeit, but 10,000 of them, that’s a different story and that’s how smaller denominations are packaged and sold.
