I did attend one dig in pontypool park which was run by the gwent detector club
we were allowed down at pontymoile park gates end and could detect up as far as the stadium...but not allowed on any of the "lawn" areas there were loads of viccy silver georgian coppers and one roman bronze came up we detected up the tree filled bank
and around the old fair area loads of pre decimal coppers.
I did find a roman coin myself at the mountain village of Pantygasseg it was an as
of hadrian...found on the surface after a rain storm .
I tried on a later occasion to get permission to detect in the park area officially and it did
progress quite far until they asked the opinion of the county Archeologist who reccomended that permission should not be given in case i disturbed stratified layers!
I had volunteered to donate all decent finds to the then infant museum anyway but sadly
was stymied by this official...Regards Paul Baker.
PS once found a lizzie sixpence on an old drovers route on a mountain top between
Cwmtillery and The Varteg.
