US Scott #329

Continuing with the Jamestown Exposition from my uncles collection. The top 2 stamps in this block are imperf. Can anyone tell me whether these were made this way or if you think they are cut. It appears to be a manufactured edge to me. I see no reference to imperf edges in the catalogue so not sure what to make of these. I have a US Scott #330 that also has an imperf bottom edge that I am sure is a manufactured edge.

the top two are just straight line, margin copies. that's where the the sheets was cut apart. imperforate refers to a stamp with no perforations at all, usually intentionally by the issuing entity. I hope this helps clear things up a little bit?

Yes, thanks. So when determining grade does this get evaluated the same as a stamp with perforations on all 4 sides? Or does the lack of the perf on the one side make a difference? Just posted the US 330 example before I got your response so please forgive my inaccurate reference on that one.

It makes a difference. It hurts the value. Usually the value of a sound and nicely centered stamp is valued at around 10% of catalog value in "real world" prices so would come in a little lower. However, it is the high value of the set so as long as there is no other faults you could expect around 10% of catalog value on a good day to the right guy.

What's a little odd though is there is a guide line down the left side perforations but sheared up top? I reckon it was separated into 2 sheets of 50 (top & Bottom) and oriented and perforated and just separated between the bottom two? I'm on my way out the door at the moment I'll finish up when I get back. If someone else don't chime in first.

The line on the left is the center-line, Jeff. This block is taken from the right side (position 6 & 7, etc) of the bottom sheet of 100. The bottom sheet would have plate numbers, imprint, and guide arrows on the bottom of the sheet, and nothing visible on the top margins.

Jeff pretty much nailed it on values. Generally speaking, natural straight edges are less desirable.

Yep Brian I was actually thinking about that through town earlier and figured it out. I was thinking definitive size layout vs. the commemorative stamp dimensions' layout..(Does that make sense to you?) I was just typing literally as I was getting my coat on to leave...forever the stamper huh? lol Thank you for that I just couldn't see it in my head. I thought the margin/selvage was just separated on that side (via perforations) but it all makes sense now.. :)
