The most important thing to ID these is the portrait class type (Which I can't help with, other than its 'with Sceptre' & not without) & the Moneyer & Mint, because all shortcross's have the obverse legend HENRICVS (Henry II, Richard I, John, & Henry III).
So you have the reverse Moneyer & Mint as;
WALTER.ON.LV
Which is Walter of London, which gives you 2 possibilities King John or Henry III. You need an expert to tell you the difference. (But I'll go with King John)
