Colombia 5c With Wildly Repunched Date

Here's a fun coin I found at the show.
Apparently for Colombia in the 50s-70s, such wild repunchings were more common than not. Still, it's a very entertaining piece because not only were the digits repunched, but they used several different punch styles! Here's a breakdown of the photo below:

The 1 digit was punched with a large, sans-serif numeral over a shorter, serif numeral--check out the flare on the base of the underlying 1!

The 9 digit was punched at least 3 times! There's evidence of a digit east, then an underlying 9 with a flatter bottom stroke was finished with a 9 where the stroke curls upward. At least 2 digit styles again.

On the 7, there's a straight downstroke underneath a more curved 7 digit. Any ideas why the coin field is depressed around this digit?

The 0 is a bit lower, but at least it's completely on the die!
I've seen a few coins where several digits run off the edge.
There are traces of a second 0 NW of the top digit.

Do you suppose the mint in Bogota was very concerned about the date on these coins?
But thank you Colombia for making repunched dates so intriguing!
