Old BYOC Kits

[LowRent]

I have 3 unbuilt kits from BYOC, all 10 years old.  My intent is to sell them.

Is it permissible to inquire here about their value?  I won't post what kits I have until I've confirmed this is acceptable.  If it's not acceptable, would you kindly suggest where I may inquire?

Thank you.
