Which mint error type is this?

Hey guys, I recently got this Sudanese mint error in the mail, and I'm still a bit of a novice when it comes to certain mint error types, so I'd appreciate some help ID'ing the specific error type.

I know the reverse is a pretty simple slight off-center strike, but the obverse is what I'd like some pointers on.

Also noticed the picture used for this coin actually pretty much has the same errors lol

N#12557

Denomination side looks like a collar error:  Wide Collar (error-ref.com)

The radial splay marks (flow marks) on the other side are not at all rare (fairly common on Jefferson Nickels), but I am not sure what causes them.  I would think this means the metal is resisting flowing properly, so maybe it is low striking pressure?

Thanks for the insight!

With a little more research …

These marks can be an indication of die wear.  This is consistent with poor details of the devices on that side of the coin.
