FREE: Canada Proof-like 1867-1967 Commerative Silver 10 Cents

This may help explain this for you. "These were made in such huge numbers, and being a very popular one-year-only type, that they were saved in huge numbers. Unless it is in uncirculated condition ($4 and up depending on how nice), it's only worth the silver in it. Except that for only a single coin, a dealer isn't going to bother." "During 1967, Canada lowered the silver content for dimes and quarters to 50%. So, both 80% and 50% exists for 1967. The 80% dime has about $2 worth of silver, the 50%, $1.30. It is almost impossible to tell them apart because, unlike other coins where the composition has changed and the newer coins weigh less, the difference in weight between these two dimes is so tiny that most scales can't pick it up. That's why when you go to sell 1967 dimes, buyers won't pay more than the lower price."

The 50% coins of that year were made in a limited number so chances are this is 80%. Besides I've seen this coin go a lot higher. And this is uncirculated FYI.

What's the deal with my silver coins doing so poor?

This^ 1968 quarters are also the same way for Canadian currency, the 68 Quarter has two variations, both 50% silver and 90% nickel I believe, it is hard to tell the difference without doing the magnet test, I have heard you can do the "ping" test to tell the difference between the 50% and 80% 1967 coins, you basically take a 80% silver 1966 and older canadian quatrer, and a 1968 quarter that you have silver tested, it will be 50% drop them both on a table individually and listen for the sound differences, you can then somewhat train your ear to tell the sound difference between the 50% and 80% coins and be able to more easily determine the silver content in your 1967 Canadian coins.
