It's the common 534, with a New York double oval Hudson Terminal cancel and worth a couple bucks. 90% plus have a simple machine cancel with only the wavy or straight lines visible. Most collectors find the heavy cancels undesirable.
I find that 5 to 8% interesting and collect them. I'd be interested if you want to sell it.
