Identifying US 2 Cent Navajo Jewelry Stamps By Plate Position Schematic

I have enjoyed the low denomination American Design stamp series. IN my pursuit of collecting coils and panes I found the 2 cent Navajo Jewelry panes rather a challenge to get all plates from various years. In particular the S1 plate from 2006.

Identifying each can be a little tricky as the year of its first issue 2004 shows as the copyright date in the selvedge of the pane. Also, the 2004 V1 has the most vibrant blue coloring while the rest the shading difference is found in the "whitish" areas of the jewelry design. And lastly one reprint has microprint the others do not.

But I found the easiest way to determine which version they are is by plate number and the schematic given in the pane. V1 dated 2004 has a plate position schematic of a horizontal rectangle with 14 positions (2 boxes high, 7 wide), S1 dated 2006 has a plate position schematic of an almost square rectangle (3 boxes high, 4 boxes long), P1 dated 2006 and w/microprint has a horizontal rectangle divided into 6 boxes (2 boxes high, 3 wide), and S1 plate dated 2007 has a plate position schematic of a vertical rectangle (6 boxes high, 2 across).

So sometimes the plate position schematic can be very helpful in identifying Scott numbers given to subtle varieties of a particular stamp that has been reissued over several years.  

As a sidenote, the one Scott number I have NOT been able to get from post offices is the 2006 S1 and this may be because of there are two varieties caused by where the die cuts fall. Possibly plate collectors have hoarded these after the varieties were discovered years ago.

For those who work off Scott numbers, what chris s refers to as V1 2004 is 3750, S1 2006 is 3751, P1 2006 is 3752, and S1 2007 is 3753. An additional note on 3753 is that it also has microprinting, although in a different place than 3752's (the left side of the stamp in one of the necklace "extensions", for lack of a better word, instead of on the right side where 3752's microprinting is).

I also do not have 3751 in my collection, so it must be a little hard to find. Although, according to my StampManage software, 750,000,000 stamps, or 37,500,000 panes were printed.

Mstocky2 - thanks for this great link.

Yes 3751 is of all the American Design stamps the hardest to get. Therefore, you end up paying a higher premium for these. I would not say they are scarce but uncommon because their print run was short.

Also beware of covers that advertise having Scott 3751. I have found that some sellers misidentify the stamp on the cover as Scott 3751.
