Selling your collected treasures.

I had a couple of guys come by the shop today to sell me some items that they have collected.  They just wanted what money they put into them and were befuddled when I told them that I would give them 1/3 of there current value.  You see they didn't understand that dealers have to double or triple their money.  We can pay up to 50% of the going price if it's a quick seller.  We have to clean, repair, price and display the item, let alone pay for rent, supplies and any banking fees involved in selling.  Some times it is a gamble to buy an item we are unfamiliar with.  Well there you have it!  Please be realistic and adjust your thinking to the reality of the market.  Not sure what amount to ask?  Check with your reliable Certified Appraiser.
