Seated 25c guys........a little help please

Maybe it's my eyes but do these 1840-o Seated quarters look like they have the same Large O mintmark? The one on the right has been harshly cleaned but to me the O appears larger?? Any comments are appreciated! Both are No Drapery Reverse B examples.

That could change however.

The variety to have your large O on is the 1840-0 "with drapery."
