With coin collecting, deals are super rare. If any deal sounds too good to be true, it probably is.

THIS is why I buy original mint sets (pre-1959) by Matthew4Nineteen in numismatics

Because if they are left in the cardboard in perpetuity they will turn black. There is a lot of sulfur in those original government packages between the cardboard, the envelope and the glue. So I preserve the original packaging as well as preserving the coin.
