I love it when they say auction estimate, insurance value, or retail price. The only one that is accurate is the insurance value and that is only good if the object is stolen, damaged by fire, hail, wind, water, or ? That insurance covers the replacement (hopefully) cost of replacing it with an identical item RIGHT NOW. Some items, of course, are irreplaceable and you will never find a like item on the market anywhere at anytime (such as a one-of-a-kind woodcarving that perishes in a fire).
The auction estimate is only an estimate and the item can go for more, less, or go unsold. Fees must be deducted from the auction venue.
No one will pay you a retail price but a gallery would sell you an item at retail. If they sell your item, they will charge a commission or consignment fee.I agree with mart, most selling prices should be half of a quoted price or even lower. On common items, one would be lucky to get a tenth of the "value" and on really rare, great items, one could get twice the value or even more if the demand is there.
I love it when I see something I am interested in and the seller says "someone said that is worth X amount of dollars" so that is what I want. The "someone" should pay the seller that amount then. Ain't gonna happen.
