Recently I approached someone to metal detector their back yard. They said yes and I went to the site a couple of weeks ago.
I found a lot of cool things including two predecimal coins, 43 decimal coins (a lot of which was on the surface!), a couple of dog rego tags and a belt buckle. As per my policy I left all the items for the property owner, however they only wanted to keep the coins.
Today I polished up the rego tags and belt buckle - I think they turned out OK.
The other items...
