Establishing equipment value?

I am liquidating my workshop and have stakes, hammers, mandrels,
buffing wheel, kiln, enamels, etc. for sale. How does one establish
a value and then sell these types of items? 

Make an itemised list. Work out a job-lot price and/or groups of
items.

I might be interested in some things and I might offer you a price
for this and that plus some other things that I would like but
probably wouldn’t buy and wouldn’t offer much for.

If you price everything individually you might get people picking
through your stuff. Someone who is interested might buy the whole
lot. When I set up I bought pretty much everything a closed business
had.

Email me a list if you like.
