I got a free upgrade and got the 4s for free with verizon.  I used it for 2 months but just received the new Iphone6 plus as a gift for christmas

Is the Iphone 4s worth selling? someone said I could get like 30$ from those trade in sites but was wondering from someone who deals in phones if this is worth trying to sell to an individual. Phone works perfect and has a case no scratches. Even the head phones are still wrapped and brand new


any imput would help

thx
