[Boatanchors] back issues of Electric Radio magazine?

[w4ron at carolina.rr.com]

I've got 12 or 15 years of Electric Radio magazine that I'm
considering parting with. 
I have 1998-2012 only missing 3 issues, I also have some from
1990 and a dozen more mixed up issues.
Can you guys give me an idea what these are worth?
Should I sell them as one lot, or individual years or how?

I looked at the ER web page and was surprised that they want
$3.75 for back issues... 

Thanks for your help.
