This is awesome! I never expected to hear from a relative of the creator of the Victoria Gardens. WhatI have derived from this information is that this token must have been minted in the early 1850's when the Victoria gardens were located in Bury. During the late 1850's, the gardens and Hamilton museum moved to an unknown location where they eventually closed in the mid 1890's. I've located many tokens from this time period but only one other token like the one I've pictured. Many of the common tokens of this time frame appear to sell through on line auctions in the under $10 range. More unusual token from this time frame with the young (duck head) queen Victoria sell for $50 to $80. I'd be interested in finding out if others have this particular token or is this truly one of only a few known examples.
