Can Anyone Identify The Class Of These Shortcross Pennies?

Thankyou guys! what a nice welcoming forum : )

I'm not an expert but this website will help: https://www.rodblunt.com/short-cross-pennies-2

I would guess they are John, class 5 or 6, because of the hair curls (2 on each side), 5-pellet crown, good chin and neat beard with central pellet. Both seem to be from the London mint.

The 2 curls and cross pattee initial mark put them class 5b, 5c, 6a, 6b or 6c1.

The X in Rex seems to rule out 6a1 and 5c, and the eyes rule out 6c. The beards look neat with vertical whiskers, so not 6b. That leaves 5b1-3 and 6a2.

The one on the left has a normal S and round-topped R, so could be class 5b2.

The one on the right is missing useful bits of the legend, but the large pellets on the crown suggest 5b2 as well.

Is there anyone out there who can identify these two coins? : )
