Allengelhard lists the slightly larger old logo on 10oz PM bars being different - quite similar to my eye

Is it the same with the 20ozers? I have a growing collection, and think I have 2 that have a larger stamp, but could just be natural variations I'm not an expert.
The 2 on the left (i.e. two top ones in this pic) I reckon are bigger
And here is a side by side
And just for show - the rarer modern stamp
