Good score, found one this past summer in Ontario not in as nice of condition as yours.
Bank tokens were common trade before 1858. All banks had there own, the day I got the Upper Canada token I scored a 1844 Bank of Montreal token.
Yes the penny is Englands influence and no longer in use.
In 1850, the Bank of Upper Canada received the right to issue a coinage due to a severe coin shortage. The coinage consisted of 1/2 Penny and 1 Penny Bank Tokens. The obverse of the coins carried a representation of St.George slaying the dragon based on Benedetto Pistrucci's gold sovereign coinage design. The reverse of the coins carried the then obsolete Coat-of-Arms of Upper Canada. The 1850 issue was struck at the Royal Mint, London, but the coins did not arrive in Canada until 1851. Some of the 1d. pieces bear a dot between the tips of the cornucopiae, but the significance of this is unknown. The letters "R.K. & Co." is not a mintmark. It is the mark of Rowe, Kentish and Company of London, the agents the Bank of Upper Canada used to place their coin orders.
In 1852, the Royal Mint started to strike the second issue, but due to a heavy schedule and time pressure, the coin dies and planchets were transferred to Heaton's Mint. There is a way that the strikings can be distinguished. The Royal Mint issue has the dies in medallic alignment, whereas, the Heaton's Mint issue has the dies in coin alignment.
