Great eyes to spot it. Series 2013 has an abundance of that type. I see a lot of those heavy ink on the third digit and its a minor over inking error. Personally I saved a few of the 2013's when I first noticed them, but after a bit, I realized how common that type of "error" really is being found at least for that specific series 2013 and ended up keeping only a couple that just look interesting for a currency collection. Initially they were/are selling for a few dollars over face value to casual collectors say 2-3 bucks and probably still do if you check ebay sold listings, but generally the thought is that these should not have too much value over face due to just how common they are, especially series 2013 where its very common. Apparently I wasnt the only one as theserialflorist also posted a bunch from that series http://goccf.com/t/438192
Obviously if its on an earlier series where its not common or the note is uncirculated that may make the note more desirable to collectors and perhaps have some slight value add. In the case of a 2017 series that have also been posted, its unknown which if any of these errors will have any demand pushing up value yet and how common like the 2013 overinked serials will be. Since 2013 there is the new printing machinery being used so things are different than before 2013 and new problems always pop up with changes. I think I mentioned the ink bleed/smudging issue found on some 2017s here http://goccf.com/t/440922
These kind of finds also are great for beginner collectors also since they will pop up in typical circulated currency and also helps some people get interested in currency or errors on currency and collecting them. At $1 saving a few would be my recommendation and its a cool find
