Apparently, there were three different types of dimes issued in 1968. The first, 1968 silver version. Easy, peasy. But the other two have me perplexed. There were also two varieties made of nickel. One has the Ottawa reeding, the other has the Philadelphia reeding. Can anyone lead me to or have info on the two types of reeding? Thanks in advance.
Yes the silver 1 is .500 silver The other 2 nickel. The US mint Philadelphia mint edge grooves have flat bottoms. The Royal Canadian mint edge grooves have V-shaped bottoms.
Here is a link to see what the difference looks like... Link: https://www.gosling.ca/1969/ Scroll down and you will see the 1968 coins...
Also if high grade the canadian clad versions are very shiny and reflective,the silvers usually have a white light pastel appearance.
Actually you'd be surprised that from 1968 to 1999 it was pure nickel besides the silver version.Then in 2000 to today they switched to nickel plated steel.
Actually, until I got the folder for the newer cents, I was surprised how many varieties there were. No mint mark, with mintmark, copper plated zinc, copper plated steel. Boggles the mind.
And, if you are into errors, there are rare 1968 Canadian 10c coins struck on US 10c clad planchets. Here is one I handled recently.
