1953 Canadian Silver Dollar SF,FWL, now the Queen has a shoulder strap. Coin has the same trend value as the NSF, I always thought this was strange, one would think the NF would have a higher trend.
The other 1953 varieties 1953 NF,SWL and 1953 SF,SWL are the harder of the 1953 Dollars to obtain and have a higher trend value and also have not been recorded in above MS-63 condition.
