1977 Helix Star Wars Felt Tips Valuation

[elv_1986]

Hi, I would like to value my collection of 1977 Helix Star Wars "May the force be with you.." Felt Tip pens. I have a large quantity of the pens in good condition, but sadly not in original packaging.
How do I go about valuing these please, and possibly selling depending on their value?
Kind Regards

I would suggest that you have a look at sold prices on eBay or Facebook groups that deal in these items.
"Star wars beyond the toys" on FB would be a good place to start.
