Mystery solved.I send pics to guy specializing in early and medieval coinage.Here is the answer:
Dear Sir, Thank you for your enquiry. This item is not a coin but a
privately made 'token'. They range in date from about 13th century through
to Tudor/Stuart times in lead and pewter. This is one of the earlier types,
perhaps 15th-17th century and, as usual, it shows a crude design that, in
this case looks to be a monogram of the initials EB (with E backwards) to
one side and a crude letter W to the other. I think I have seen this type
before. Although they are interesting, very little is known about the
circumstances under which they were made or who issued them. Some might
very well have been used as piecework tallies (similar to the 18th/19th
century Hop picking and alike tokens); they could also have served as a
crude form of small change on a local basis. They are generally common and
have negligible commercial value. Regards, Chris Wren
Thanks again Chris

At least I was right with monogram W
