Close. Condition is important too. $5 Take a look here: http://www.coolserialnumbers.com/FancySerialNumbers.aspx
Trinary is not a term that serious note collectors pay money for. It is a made up term by You Tube videos to make you think it's worth something. There are 8 digits in a serial number and millions and billions of notes are printed, there are so many combinations, trinary is not any kind of a big deal. There's no trinary serial numbers in the link. It's worth $5.
Despite the 5 straight 7's there is nothing fancy about it. The condition is next to terrible and condition is everything so it's a spender.
