Help request - D. Afonso V Chinfrão

[palves]

Hi everyone, 

A bit off-topic but, I think, still relevant. 

Together with a friend, we are conducting a study on the Portuguese coin Chinfrão (D. Afonso V 1438-1481). These coins often appear in the United Kingdom and B. J. Cook even argues that they might have had legal tender in England "Chinfraos seem to have had a not insignificant currency in early Tudor England, as a number of finds attest. (...) Perhaps Alfonso V's
chinfraos had, in some unrecorded way, been given a legal or tolerated status." in B.J. Cook "Recent Tudor Hoards"

I am coming to you to ask for any bibliographic references, findings or any other material related to the Chinfrão.

Thanks in advance.

well the coins back then were valued on silver weight, so a coin of similar metal, size and therefore, weight would be taken as legal tender, I see a few Metal detecting find lots on Ebay seem to have coins of Venice, so what we probably see are people trading, bring back the currency and use it. Remember also that Portugal is our oldest Ally.
