Query Regarding Silver Solder

I have 6 rolls of silver solder from years ago

500g rolls
99% tin
0.3% Silver
0.7% Copper

If my cals are correct each roll contains

495g tin x 6 = 2.97kg
35g copper x 6 = 210g
15g silver x 6 = 90g

Is it worth the bother to get this refined or should I sell it for its spot weight?

Thoughts?

 

I can't imagine it would be worth refining for 7 ozt of silver. What is it worth in it's current state as solder?

Edit: damn, should have checked the maths

 

.3% of 500g is 1.5g so 6 rolls gives you 9g silver.

Not worth it IMO.

 

Probably better off selling the solder on ebay and then buying silver with the profits

 

oh damn forgot one of the zero's lol

worth about $11 of silver lol

 

I reckon even Yellowcake has a higher percentage of the active ingriedent than your silver solder.

0.3% Ag- leave it in there and use as SOLDER only
