I looked at the example on CoinsandCanada.com .
All your features agree with that example BUT-----I contend that your example was mis-struck (probably a planchet flaw) . Part of the feature did not adhere to downward stroke of the 5, balled up molten and fell into the crook of the 5.
All in all ---I would say it was a 5/5, but you will have to convince the world with more science and closer study---good luck for your find. ! Tell us what you finally decide.
