SOURCE: what is the value of my admiral sewing machine

Hi. The value of any sewing machine is purely subjective. Sewing machines were made by the millions and the ones made prior to about 1970 were generally extremely well engineered, constructed of metal, and--with just basic, routine maintenance-- will last for many decades. All my regular sewing is done on machines that range in age from 50 to 90 years.
Machines like yours aren't at all rare (sorry) but there are people out there who do like the old machines. You can look on Ebay to get a feel for how much people are willing to pay for machines like yours.
Sometimes a machine, such as Singer model 221 Featherweight, will become valuable. Quilters love this type of Singer because it's small, lightweight/portable, and has a marvelous stitch. One in excellent (meaning showroom) condition might sell for $400 or $500......but I could find any number of them at garage sales for $25.00 or less! (And there are lots of sewers out there who don't like them because all they do is straight stitch.)
This probably isn't what you want to hear. . . .
