Question on shipping

[Mechanic688]

Alright, because I was wondering how you can ship out a single coin or some box tops

I have some LED's that I sell on Ebay and when one sells I put it in a regular envelope with a .70 stamp. Why .70, cause that tells the P.O. that it has to be hand stamped and not run thru a machine. Course in the listing it is stated that "This LED will be shipped free in a standard envelope so there is no tracking # available. This helps keep the price down". A coin I would fold it up in some note paper to protect it.
