Hi Jim, good pair! These are two different Franklin 1 cent designs.

The one on the right is the 1890 issue, Scott 219.

The one on the left is the earlier Bank Note design from the 1870s, and that one takes a little more detective work, because the same design was printed by several companies and catalogs under different numbers (134, 145, 156, 182 and the re-engraved 206). Flip it over and check for a grill (a small waffle pattern pressed into the paper). If there is no grill, the paper and the shading lines on the front narrow it down from there.

@jblaha would love your eye on the left one too.

@ryanjoneson no problem.

@california-kid Jim, I downloaded the photo upon your Post, specifically the left-hand image and am unable to see any indication of a Grill.

Not taking into account the Light Test, and the Flick Test – Let me know whether you desire to know more about these methods for determining Hard or Soft Paper – Here’s my quick assessment…

Checking the Pearl to the left of the numeral “1” of the image upon your Post, I have exploded this area and have enhanced it as best I could, though it remains quite blurry, there appears to be a faint “DASH” within the Pearl, this is the “SECRET MARK” (see exploded images below):

I recommend you check this with a Magnifying Glass or Loop to ascertain whether you see this…

Now, looking at the upper left corner of your image, it appears there is shading added to the Pearl and Arabesques, again here are the exploded versions:

I recommend you check this with a Magnifying Glass or Loop to ascertain whether you see this…

Based on what I can see from the above two exploded images, though blurry leaves me to assess this as US Scott # 206.

My reasoning for this assessment this is US Scott 206 is due to the “SECRET MARK” which is present within the Pearl to the left of the numeral “1” and the presence of shading added to the upper left corner Pearl and the upper left Arabesques.

All other versions (US Scott 145, 156, 167, 182, ad 192) have clear upper left corner Pearl & Arabesques, like this…

Let me know what you find with the Magnifying Glass or Loop. 

I hope the above proves beneficial to your needs.

Keep On Collecting

@california-kid Please let me know what you find at those points of interest, I believe I do see the “SECRET MARK” as well as hints of the Shading referenced above – although all can be faintly seen.

I recommend using your cellphone camera with the MACRO MODE (that’s the little Flower thingy) for better detail to be photographed, or a scanner with a minimum of 600dpi.  I wish I was more Tech Savvy so I could explain this better.
