Sorry ,I disagree ,something dropped and picked up is not the same as buying and making a offer ,which is then accepted .
The story is, this happens all the time now and has been going on for years .
Stamp dealer gets a call from a trustee/lawyer or a grieving widow or a rock-in-roll son who wants to sell his deceased father's collection .
Here is how I do it -----Show up ,no suitcase of stamp catalogs ,no computer ,just a light and a set of tongs . Start off saying "sorry to hear the old man died ,then the important questions ---this is key ----How much did he spend on stamps , where did he buy the stamps ? more questions, anybody else in the family collects ? Important -question --Has anybody else has looked at the collection or given a offer .
These above questions are most important to establish your attack . Then spend five minutes explaining how terrible the stamp market is these days and all the collectors are trying to sell everything on
ebay before they die .
At this point I discuss taxes the family has to pay as part of the estate tax situation . All the time I have a pocket full of hundred dollar bills , I keep thousands in each pocket ,so they don't see how much I have ,plus more in the car ------Cash on the kitchen table sounds a lot better to those in the room ,than filling out tax forms .
Now view everything , go fast and don't stop too long to show interest , check to see quality and if possible fakes , never --never act surprised or talk about a item 's value . Let them know the die guy was a advance beginner and enjoyed the hobby and that nothing there is show quality . Explain to them most of the collection will end up in your mixture boxes {show them your ad about mixture boxes of 2 cent stamps }.
Always explain the hours of work this disorganized mess will cause you to get in right so you can make your 20% profit .
ALWAYS -ALWAYS ask what they want for it ,now your going to find out who the decision maker is .
This is where you lay out the cash all across the table and tell them this is all you can pay and let them decide ----trust me here ----money on the table says more than anything you can say ---NO TAXES -CASH MONEY NOW,TODAY .
