I would greatly appreciate any information on this black stamp.
looks like a one cent Benjamin but I am new and just acquired a massive collection.
Don't even know wear to start. I have hundreds on assorted color Washington's and Benjamin's .I was wondering if their is a basic check list to go through .to weed out the none valuable items.is the size of a stamp the only way to determine the year printed??
thank you in advance for any help and advice you all can give mee
