Id help please - is this possibly Richard III?

[John O3]

I have been trying to identify this small silver coin. The obverse is well beaten up but the reverse has a strong resemblance to Seaby 6410 with the dots in each quarter of the cross and the 4 part diamond in the centre. Does anyone have an opinion as the whether this is Richard III or is too beaten to attribute to any ruler? It came with a group of medieval half pennies purchased at auction. It's 16.5 mm 0.65g

Any guidance gratefully accepted

Thanks

Could more likely be Edward IV York mint than Richard III. It may be worth looking at Irish issues of Edward IV due to the extensive clipping. In short, I don't know but I'm inclined to think Edward IV York mint.

Thanks for the guidance - I'll pursue that angle

From the size, it's a penny. Little can be deduced from the obverse, as you say, other than it's an English penny with a crowned bust facing. Likely 15th-16th century. From the reverse, I'll cite the one diagnostic device I can discern: the central device in the long cross is a pellet in quatrefoil, thus minted in York. That happens to resemble my Henry IV penny of York, though it could also be a coin for Edward III-IV, Richard II, or Henry V-VI, whose pennies were minted at York with the central quatrefoil.
