Sweden 1884 5 Ore: Re-Engraved Or Repunched Letter

Lately I've been finding many coins of Sweden with repunched letters and dates. Either they're common, or I know where to look.

Here's another example where the R in ORE shows a second outline on both sides of the letter.
For instance, the serifs appear to be extended and a few contours on the right side of R are clearly extended or doubled.
At first, I thought this might be a doubled die, but nothing else nearby is doubled.
Also, if the die were double-hubbed, I'd expect to see at least some small offset on those doubled serifs.
Instead, they are perfectly aligned outward. My guess is this letter was intentionally repunched or re-engraved on the die.
Perhaps the first impression of this letter was weak, or the die was somehow damaged? Whatever the cause, it's an interesting detail.
