I would post the pic but apparently it's too large of a file size.

They're "Nu-Tone" 371 set

E-plain steel

A-Aluminum on gut

D-aluminum on gut

E-Silver on gut

"Designed by E&O Mari, Inc. Made in USA"

I can't find any info on these online. All I can find is E&O Mari owns La Bella strings and they don't market gut anymore.

Are these worth anything or should I just use and expend them like any other strings?

The package is sealed and it's a full set. I have another partial package with an E and D string.

Thanks in advance.
