Hi forum, as you might notice this is my first post. I came here looking for answers to this question but see nothing on the topic of recent in the forum at least, so I will try to phrase the question.
As you may or may not be aware the 1922 penny has 3 varieties.
Wide date variety. Wide date toenail nine variety. Plain variey.

Wide date variety.

Wide date toenail variety.

Plain variety.

My question - is the only way to tell these apart to line the physical coins up and then gauge the 2 wide date varieties as wider than the plain, and the toenail wide date variety as having that tiny bit longer 9?
