About 130' solid copper 12/3 with ground NM-B left over from a completed project. There are no kinks or damaged insulation throughout its length.
The NM-B-12/3-CU-1000 type Romex building wire is used primarily in indoor residential wiring, usually as 20 amp circuits.
The wire is new/never used, but a bit dirty having been stored for years and spending an hour untangling it into a nice coil. This was from a 250' roll; the remaining length is a calculated estimate measuring the average circumference and multiplying the number of loops.
