1953 is the first year to feature Queen Elizabeth II on Canadian coins. Here are a couple that feature main varieties: Shoulder Fold and No Shoulder Fold (also known as "with Strap" and "without strap", respectively).
First, thanks for pointing out one is a quarter, I wrote both were halves (now edited). That's a good question. I honestly don't know. I was only referring to the shoulder/no shoulder varieties. Do the quarters also have large and small date distinctions?
Sure do. Google canadian mintages. Look for varieties. My book has two slots for the 1953's. Oh see @alurid took care of it
The cent has the shoulder strap thing, and the Nickel is a mess. First year of a new issue gets a lot of attention,and changes.
if I understand correctly the 50 cents 1953 SF type was issued with large date while the NSF was issued with large and small date, see http://coinsandcanada.com/coins-prices.php?canadian_coins=50-cents-1953-1964 For the 25 cents they don't say anything about SF or NSF, only about small and large date
Probably the information at coinsandcanada.com is incomplete.... obviously the OP 25 cents coin has a SF
