[1/2 PE]NY 1663 in three lines.
Ex D. Vorley.
M Dickinson 132A, this piece but dated 1663.
This is the only known example.

I believe this to be the same specimen that was in the William Sykes collection, which was on permanent loan to the Hull museum in Albion Street, which was hit by a bomb in the Second World War.

Below is an extract from, Coins, Tokens and Medals of the East Riding of Yorkshire by Philip Whitting:

W.132* obv: A clothed arm holding a hammer to left id. *IOHN . BAKER.;· rev: I B id. (Peweter) *OF*HVLL*1665.:· (Fewster) John Baker, pewterer, died in 1710, aged 78, and was buried in Holy Trinity Church. He is said to have been born in the Hammer in Hand inn (one such at no. 187 High Street was pulled down in 1863) and to have been known as the Protestant tinker. In 1669 he was a chamberlain of Hull. In 1665 he appears 10 have had a tenement in Whitefriargate next to the 'Green Dragon'. In 1681 the Privy Council ordered the prosecution ofJohn Baker of Hull, pewterer, for spreading false news.

"Sheppard's reference to a penny token of John Baker (in W. Sykes's collection) in H.M.P. 94 (l9l3), p. 27, is probably due to a misprint."

I believe this was a reference to this very token. At first inspection this token appears to read A PENNY 1663, however in my opinion, A 1/2 PENY 1663 is more likely, (dated 1665 in M. Dickinson).
