One thing to check out for is reproductions. Since reproductions are not well worth as much as the originals it is important to be able to spot the difference and here is how you do it.
An obvious one is to look for a stamps. Is it a 1 cent or 2 cent stamp? And then more than likely it is genuine.
Check the postmark of the postcards, if that has an old date chances are it’s an original. There are only a few reproductions out there that are that old.

Reproductions usually look too fresh, are printed on an off white color, and don’t look like they’ve been handled too much. A lot of the old postcards have on the backside of them the name of the publisher; where they were printed; and some have got series numbers as well. Of course , they could have been copied also but this gives you something extra to look for. After handling a lot of postcards you can almost tell right away if it’s a new reproduction or not.
