Nothing. The fella has some mis information. 01A would be a 40s ford reference #.
As always take another Model A guy with you and validate the points he is considering to value his car at $22k.
Also good to look up what comparable cars have SOLD for.
It may be a typo as in 31A instead of 01A. No telling what he was thinking.
The coupes are generally in the body style 45 category as in a 45B coupe. The 45A was the earlier 1928/29 types. The car has later wheels on it with larger tires so it looks a bit fat on the lower end.
