Hi everybody,
Recently I bought a little collection with used USA stamps and one of them is this 2 cents (with numbers) red 12 perf
horizontally George Washington

I have another stamp with 12x12 perf

Checking my stamp catalog I couldnt find 12 perf horizontally stamp so I think is a fake stamp.
As I can see in Scott's number, perf 12 stamp is #406 which is Type I. Looking both stamps I can't detect if they are the same type.
Are both the same stamp?
Thank you very much for your helping
