I Found A 1923 Franklin 1 Cent; Perfs 9.5 X 9.75

check back later; frustrating

Confirmation bias describes our underlying tendency to notice, focus on, and provide greater credence to evidence that fit our existing beliefs.

all 3 gauges

finally making some progress

250 kb shrink worked

you will see (hopefully soon) results using 3 gauges

white; paper
blue: plastic
black; metal

at least they all lined up per the prior pic

blue gauge

white gauge; made this one a sharper image

sharper (hopefully) blue gauge

black gauge (wish it were crystal clear like the first one)

Hopefully this enhanced cropped black gauge comes out clearer

Partime is a great moderator

He suggested I show pix using a 9.5 look

Not sure how these can be rounded up to a 10 perf

To me, they look closer to a 9.5 than to a 10

What am I missing; experts' input is always welcome

Have at it all

They do appear to be close to 9½ but between 9 1/2 and 9 3/4.

However, in the first two pictures, the gauge is not parallel to the perforation but slightly askew. Also both the white and blue gauges show that the consecutive lines shift to the right of the perforation holes going from left to right.Again, this suggests something between 9 1/2 and 9 3/4. These two things add up.

Is that also what the top shows?

Furthermore, how can the black gauge look like 10 here: https://goscf.com/t/90124#837582?

Hello Stamps2025,

For your information, I have lined up the reference using the right gauge, simply for comparison with the other two. Please note that this does not guarantee that the right gauge is the correctly scaled one. Referencing either the left or the middle gauge will provide the same results.

As a small piece of advice, it is always best to start with the BEP perforations at their given scales when checking calibrations. This ensures accuracy from the outset and helps establish a reliable baseline for all subsequent gauge and measurement checks.

Thank you for your reply

I try to be as precise as possible

Your insertion of lines over the 3 gauges was helpful

You still need to check on a specialist gauge for 10-79.
