I have produced a new guide to the identification of Richard II pennies, which is now available on my BC&A website.
If you have recorded any Richard II pennies on the UKDFD or the PAS, you might find one of them illustrated in the article. Look carefully though, as image-processing may have altered their appearance.
There may well be a few typos, wrong links, transcription errors, etc. If you notice any, please let me know by using the contact form on the BC&A website, and I will correct them as soon as possible.
