Lots of pictures......please take the time to let them all appear, it's important that you get a look at all of them.
Laid paper....has been used by many countries including the US and values range from a few cents to many thousands of dollars. It is very easy to identify once you know what to look for.
Can be vertical, horizontal or diagonal.

Here's where it gets interesting.
US #63c (with cert) issued in 1861 vertically laid paper, $9,000.00 each......Had I not known about paper types I might have missed this and sold it for the $50.00-$100.00 value of a common #63....research shows that there are only 26 of these certified by the APS (one on cover). They were issued in sheets of 200......my pair is the first new discovery since the 1960's. Who will be next ?
