Estate Sale

WOW! All that instead of just not giving out personal info? I like to keep things simple. No name, address, phone number of any kind. At flea markets, garage/yard/estate sales I just ASK if any coins and if not, walk away. If yes, make offer, no personal info, buy or not, again, walk away.
Why bother with all sorts of other numbers, names, etc. No need to. If asked for personal info, just walk away.
One more story. At a flea market I noticed a black 3 ringed binder on a table. It was sort of like a enclosed one with a zipper. I opened it and it was full of those 20 pocket plastic pages and all full of 2x2's with Indian Head Nickels in them. One page of Jefferson nickels. Asked how much and the seller said $80 and after an attempt to haggle the price down, ended up paying the $80. At home I counted 238 Indian Head Nickels and 20 Jeffersons. All were in anywhere from VF to EF grades or better.
I like flea markets.

All such places are very varieous in sales. For example in some states flea market sales are taxed as sales taxes. In some places a tax number is required to sell. Some require info for income taxes. Some are restricted as to what they can and can't sell. You really have to go to lots of them to learn little tidbits of sales.
For example at one flea market where firearms and ammunition are completely against the law I noticed an empty box of Remington ammo on the table. Out of place since all other items were dishese and similar items. So I asked how much for the box? The sellsr said about $4 for the much heavier versions so I took about 5 of the heavier versions. Naturally those were all new .38 specials. Firewroks too are illigal by me so when I see a table with bunks or smoke stuff, I just ask for bigger and better things and usually hidden in the truck is just that.
If you know flea markets there is basically nothing you can not find there. It's just knowing what is going on.
