Nick beat me to it and I usually hang onto sn's like that which I find at face.
Not much of a premium if any for the sn. But then again you never know as it is tough to price these partial ladder TYPE sn's. You also have an older note which is harder to locate with 5 fives in a row.
One thing you might be able to do is pick up a matching sn on ebay...it may take a while. SN's like that will eventually show up on the bay.
That low serial ladder is pretty cool. It is tough to find a serial under a thousand, let alone a ladder type so that is a great find! I know there are people who collect the scrambles and I would hang on to that as well. It's a shame one of those zeros wasn't a one, then it would be a 8 digit scrambled ladder.
