Assuming someone uses the cheapest way possible, a stamp is $55 cents. You then have to buy the envelope, if there was padding in it that is more even if just a sheet of paper. You need at least a pen to address it, then you have to drive to the post office to mail it which costs gas and mileage and time. Anyone selling things for under $3 on eBay is very likely losing money overall or making a couple cents especially if you get under $2
The Borat profile pic is TMI... Because of it, nothing would surprise me coming from a seller using it. Has he listed any live goats from Kazakhstan? Or perhaps a turd in a plastic bag?
What is he doing wrong? If someone doesn't want to bid 99 cents on a 1983P nickel they are free to search rolls. Sixty cents shipping is laughable. If I buy just one token the seller will probably charge $2--$2.75 for a letter envelope and 11 5cent stamps.
Yes, this is my disguise for mailing coins too. And yes, minimum postage is $2.XX for 2 ounces to mail a "non-letter" which is a tiny bubble-lined envelope. The envelope itself is going to cost $0.25 to $0.30. So, for $3.00, you can mail one or two coins safely across the lower 48.
