Total Newbie Here So Bear With Me...

Basic question...
How in the world does one find the value of a large sheet of stamps?
I am in the process of demo and renovating a home I purchased last year and came across a cardboard tube stuck in back of a closet.
It contains a sheet of 200 Wisconsin Tercentenary stamps from 1934.
I found a few on e-bay and Amazon ranging from $4 each to only $16 for a sheet of 50.
Given that much variation, there has to be more to the value than simply what shape the stamps are in.
(These are perfect and probably have not seen the light of day since the early 70's)

Somebody point me in the right direction, Please. :)

If this is in the wrong place, I would humbly ask a moderator to move it appropriately.

Here is a pane of 50 that sold on ebay for $10.99

64 million of these stamps were issued (or thereabouts). If you can buy an intact sheet of 50 mint stamps on Ebay for $4-$20 then that is what they are worth. I would check "completed" listings and not what people are asking for these sheets of 50. Sheet of 200 might be a different animal. Not sure. But certainly condition of the sheet, the stamp, the gum, and the centering all are factors in the value.

To see the current catalog value of a single or block of four, consult a Scott US catalog. A mint single is worth 40 cents by 2012 catalog or 4.95 for a mint unhinged plate block of six. But realistically, these stamps are worth less than that. They are very common. So .40 x 50 = $20 and that's probably the best you'll get for a sheet of 50, provided the sheet is intact along all perforation lines and the stamps have very fine (VF) centering and the gum is intact on the back.

A full sheet of 200 might be worth more. Your best bet is to check completed listings (Ebay or auction houses) for sales of the full sheet.

Perhaps someone else can point to a source for valuing full sheets of common US commemorative stamps.

Brookman has prices on Mint Sheets. Now their prices are high so need to normalize the values with street prices but gives relative pricing. Their price is $33.50.

These are it but I don't see any listing for a sheet of 200. 10 rows across and 20 rows down on a single paper.

The full sheet of 200 format would have to be the imperforate Farley special printing Scott 755.
Heaterman, does your sheet have perforations?

No perforations, no glue.

Heaterman, can you take a picture of it and post it here?

Thus you have a full press sheet of 200 of Scott 755, the Farley special printing (issued without gum). For value, there is one among the completed Ebay listings which did NOT get a start bid of $99.98, so there is pretty much the upper limit.

The 755 roll of 200 along with a 754 roll in the same lot sold for 140$ at the Kelleher 2013 auction.

HR Harmer has a set of 15 imperforates lot in their June 1-3, 2017 sale. These are signed by Farley. They are complete sheets of imperfs with 20/6 of the subject. You might want to give them a call for consignment value??

I think we need to recognize here the difference between a "pane" and a "sheet."

It is a pane of 200 if I'm understanding Smauggie correctly.
I'll see if I can get a picture up here.

NO, NO NO!
Press sheet of 200 makes 4 panes of 50 for retail sale for normally perforated commemorative-sized stamps. But it is a very common error to call the full units sold over the post office counter "sheets" when they are "panes".

These Farley special printings were sold in full sheets of 200 through the philatelic bureau.

Don't fight kids.
You all know what you're talking about here. It's me that's the local idiot at this point.
