Dateless Canadians

No this is not a post about Canadians who can't get a date although that does sound like an interesting topic to post about. Then again since my knowledge of Canada comes from Dudley Do-Right and other TV shows I may not be the best person to post about such things. These Canadians are coins and their dates have been worn off making them dateless. King George and the denominations are clearly visible which means these coins were minted sometime between 1912 and 1936 and that they are 10 and 25 cent coins. I bought them along with 8 other coins (a few of them being Canadians as well) at the flea market for silver value which is about right for most of them from what I've seen here. There are a few varieties, I believe, for each coin including a silver content change from Sterling (0.925 or 92.5% silver) to 0.800 or 80% silver. The 80% silver versions are the only versions listed on Coinflation and are worth about $2.00 for the dime and $5.00 for the quarter.
