Standard 4-bar FIRST DAY OF ISSUE
Digital Color Postmark: 
from the Postal Bulletin May 27th:
On June 1, 2015, in Kansas City, MO, the U.S. Postal Service® will issue the Penguins additional ounce rate stamp, (Non-denominated priced at 22 cents), in one design, in a pressure-sensitive adhesive (PSA) coil of 100 stamps (Item 786200) and also a pane of 20 stamps (Item 117700).
The stamp will go on sale nationwide June 1, 2015.
This stamp from the U.S. Postal Service pays tribute to the majestic emperor penguin (Aptenodytes forsteri). Largest of the penguin species, the emperor stands over three feet tall and can weigh more than 80 pounds. Emperor penguins dive beyond 1,500 feet — deeper than any other bird. The stamp art is a stylized drawing of a pair of emperor penguins on a cool green background. The pop of orange and yellow on the birds’ beaks and ear patches lends a regal look to the aptly named emperors. Art director Carl Herrman designed the stamp, which was illustrated by Nancy Stahl. The words “ADDITIONAL OUNCE” on this stamp indicate its usage value. Like a Forever® stamp, this stamp will always be valid for the rate printed on it. The initial price and value for this stamp is 22 cents.

From Oneco CT USPS Maurice Bessette
USPS item 7862 Coil of 100 $22.00
(800)STAMP24 doesn’t have this yet, possibly a strip of 25 786203 $5.50
Today’s Postal Bulletin has the Digital Color Postmark. I spoke with the folks at (800)STAMP24, and There Is No Strip of 25 off the coil of 100 for the Penguins,
and USPS Item 786203 doesn’t show up on USPS.COM. Maybe the folks in the PNC club can get Mr. Al at the P.O. in Minneapolis MN to split some coils…
(Marty Hatton of Minneapolis MN has retired…)
I spoke with Al at the USPS Minneapolis Stamp Shoppe, and he says he is No Longer Allowed to break coils to sell strips.
I’ve sent inquiry to the PNC3 web site…

Seems the USPS is reviewing it’s Minimum Order Standards. Will see what happens
I was at the post office today and I asked for 22c stamps. I was given the Penguin “Additional Ounce” stamps. The postal clerk told me they would always be worth 22c.
However, later I checked with the USPS site, and they say in more than one place that “Additional Ounce” is FOREVER. I also see above (from Postal Bulletin May 27th) that this stamp is like a FOREVER stamp.
April 2016 Update: I see that these stamps have gone down in value with the April postage decrease. Obviously then, these are indeed FOREVER stamps.
So Honest Abe and before him the Father of Our Country (and any other especially noted ex-president) have been relegated to history, in favor of an animal species that is not even native to North America? Just wrong.
