I'm not sure that brass coin from the trick shop is a provincial coin. For one thing it has a patrician's head and an ankh on it, which suggests that it's from AM, rather than provincial.
There are also coins that have been around longer ( I've found brass, copper, silver and gold) which all share a description of 'The <metal> coins show a head on the reverse, and a tail on the obverse.' I think these may be a better candidate for the provincial coins. 18.104.22.168 16:29, 28 December 2011 (UTC)
