Henry VII Penny, York Mint 1485-1500

[Citizen H]

in take of breath........

So looking through everything and believe that this is a

Henry VII Penny, York Mint 1485-1500

Weight 0.5

obverse side completely rubbed 

the reverse side shows keys below the shield... so York Mint.

so is it by chance Spink 2235 ? possibly rare?

I have also found it to be called a "sovereign penny" but unsure if this is correct.
