Value Of Plate Blocks Of Four Stamps

I have a single 5 Dollar stamp from The Columbians series. I've seen the value at approximately $3900.00. I also have a plate block of four of the same stamp. Is that worth four times the single stamp or more? I also have a plate block of proofs on paper of the same stamp. Are proofs from that era valued the same as stamps?

Scans would be good ...

It would be difficult to scan. I actually have a single stamp of every denomination in the Columbians series and also a block of four of each of the stamps in the Columbians series. Assuming the condition is the same for all the stamps, are the blocks of four valued at four times the value of the same single stamp or does the block of four have a greater value than four times a single stamp?

Again, a scan would be nice. Your original post was about the $5.00 stamp, and you wrote that it was a plate block. Yes, the value is probably greater as four singles, but it depends on several things. That is the reason for us asking for a scan. One thing you can do is go to ebay and search for your stamp as a plate block - that would give you an idea.

I also had a question about proofs. I know there are proofs on card and proofs on paper. Do proofs have the same value as the stamp?

No. Not as a general rule. I suggest you look up your stamps and proofs on a website by one of the larger auction houses. You will get a much better idea about all this.

Scott 2016 lists the $5 Columbian as a single at $2400, never hinged at $10,000, no gum at $1200 and block of 4 at $12,000.

The Philatelic Foundation has certified 17 blocks of 4 of which 2 of have since been broken up. I do not know if any of the blocks have a plate number.

$5 plate on card block of 4 at $2150.

That has to do with the placement on the selvage and the collecting format of that day.

The Plate # + Inscription + Letter(s) stretched across 4 stamp selvedges, with the Inscription covering 2 stamp selvedges. Trying a format of plate block of 4 would have meant breaking across the Inscription.

Therefore, the formats used were margin strip of 4 or block of 8 to cover all the selvedge markings.

Some only wanted the Plate # and Inscription, without regard to the letter. Hence the format of margin strip of 3 or block of 6.

Either way, too rich for my blood! But I agree...

Thank you khj for answering a question I had and then deleted too soon when I realized the plate number on Columbians is quite different from the plate numbers I am used to.

Good question good answer.

$4 crimson lake at $2,000, never hinged $7,000, no gum $1,000, block of 4 $10,000.

A picture of any one would be helpful especially as you are talking about the $50,000-$100,000 range more or less.

When the pictures show up, I bet 25c that they are of the 1973 Compex card.

As khj has stated in his comments about the plate number and inscriptions the chances of blocks of 4 with the plate number are on the low end.

I suppose a block of six could at one time have been broken up due to separation or just to obtain two singles.

Good pictures showing why plate blocks of 4 would not be the norm.

Where are the pictures or scans of all of these supposed stamps?
