That line was just used for alignment -- it's not exceedingly rare to see it on a bill. In circulated condition, value at about $2.00
The 1935 1 Dollar Silver certificate is worth about $75 in fine condition - without tears. A note split in half may still have some value, but not much.
I also have a series 1935 one dollar silver certificate with yellow seal (African War Circulation) that is separated in half but I have been unable to determine value; Now I know there are other similar bills out there.
All silver certificates have blue seals. You also did not provide your note's denomination, so I assume it is a $1 bill. If so, it would retail at $2 or $3 in circulated condition, up to around $20 if uncirculated.
At most $1.75 - $2.00. A dealer will only pay face value for a worn bill in this series as they are fairly common among collectors. As you've seen from other posts, a bill's serial number is unimportant to determining its value.
The yellow seal notes were issued in N. Africa during WWII. In poor condition, it is worth an average of $15, average condition-$35, perfect condition-about $125.
Please check your bill again. The last red-seal $1 bills were dated 1928. If your bill is dated 1935A and has a brown seal along with HAWAII printed in various places, it's a special bill printed for use during WWII. If that's the case, please see the question "What is the value of a 1935 US 1 dollar bill with HAWAII on it?"
They can easily be found for under $5. Despite the age, it's still extremely common and not especially valuable.
Brown seals were used on bills printed for use in Hawaii, so they could be identified and demonetized if the islands were captured. Red seals were only used on U.S. Notes at that time, but the letters R and S were printed in red ink on some standard blue-seal 1935A certificates. "R" indicates that the bills were printed on regular banknote paper, while the "S" designated experimental bills printed on a different kind of paper. "R" bills have gone for $35.-$125. at auction, while "S" bills have sold for somewhat less.
The US issued both $5 and $10 silver certificates with that date. Please make sure your bill has a blue seal and the words Silver Certificate across the top, then check one of these questions: "What is the value of a 1953 A US 5 dollar silver certificate?" "What is the value of a 1953 A US 10 dollar silver certificate?"
