Well I go back well before the age of the computer for data collection.
I have some records but many of my finds even precious metal ones, I have given away to Farmers and friends.
Some of the more important ones are in museums.
I just enjoy the research before the hunt and after with identification, plus of course swinging the detector in the fresh air.
I have over time had some lucky finds, but my advice is dont give up the day job.
Happy Hunting,
Jerry.
