If you look at @pepactonius nice 1475 coin posted 12/30, you'll see that the late 15th c. 5 looks like a 7. The 7 looks like an inverted V, and the 4 looks like an inverted Greek gamma (between then and 30 to 50 years later, the 5 will grow a hat, the 7 will rotate 45 degrees clockwise, the 4 will rotate 45 degrees counterclockwise).
That should make it all perfectly clear
I think it does hahaha, those medieval guys really did it differently than now.
