Random questions about stamps
I don't know a whole lot about stamps so I'm going to just ask a few questions off the top of my head.
What does it mean when the term "thin" is used? And can it apply to a part or the entire stamp?
What is the significance of colored cancellations, red/blue/etc.? Does that make them better/rarer/more expensive?
Would it be fair to assume that a cancel mark encompassing a lot of the surface area is less desirable than one that is less obtrusive?
I get what a grill is. But what generally should one be aware about them?
Not sure if anyone can ballpark but what would it take to buy a complete set of used 19th century stamps, with the least or no varieties? Not exactly even sure what the question fully means in my mind.
