I just found a George Washington one cent stamp laying in a drawer with pencils and "stuff" rolling over it. On the internet I found out it is a Scott some number from 1914-1917. I don't know how to determine the perforation or waterstamp. I have seen some prices on the internet that has me a little nervous on how to treat this. Although as long as I don't throw it away it can't be any worse that how it has been treated for the last 90 years! Any help you can send my way on what to do to verify what it really is would help. I have a picture, but no cord to transfer to the computer with me. I'll post a pic tomorrow.
