for me its an escape from the pressure of work,out in the field you can see so much around you all sorts of wild life, and when you find some thing not just a coin its then you start looking into the history of it, i found a token a few months ago it was a port sea promissory token with a george and dragon on one side and a ship with a salmon on the other,i spent a while on the net and found it was made by 3 pub landlords in Portsmouth the ship the george and dragon and the salmon was the name of one of the landlords' was then looking into wether the pubs still existed,i think it was called the original beer token so its the thrill of the looking into where these items come form.
