T206 Miscut Question
 

How can I determine whether this is a factory miscut or one by an amateur who doesnt know how to cut straight? ;)

I would say factory due to both top and bottom having same cut angle

I am actually leaning amateur. The right side does not look straight, neither does the bottom.

The bottom cut doesn't look straight. The top cut is also at a steeper angle.

Amateur.

I think it's factory, but the second most likely option is hand-cut from a sheet imo. Very rare for a t206 to be as tall as this would have had to be in order to be trimmed in this way.

I have this similar Marquard in my hand-cut collection:

The two short corners are also extremely sharp, unlike the other two that are rounded. I think that it's unlikely that two corners could show that much wear while the top left is razor sharp. I would vote trimmed.

A diamond in the rough may just be a rough diamond.;)

Factory, the sheets were first cut into vertical strips and then cut horizontally, dull blades and other factors created the skewed cuts top and bottom as they pulled the card out of square and created the diagonal cuts top and bottom, which are often nearly the same angle but not always, depending on whether they were at the top, bottom or middle of the vertical strip.
