The USPS has been selling "forever" stamps for first class mail since April, 2007. All first class stamps sold by the USPS have been "forever" stamps since the beginning of 2011.
There hasn't been any reason to buy 1-cent stamps to make up a postage increase for about 5 years, unless you didn't bother to buy the "forever" stamps.
The only stamps I had were 42 cent stamps and a roll of 1 cent stamps. I checked online, and it said that a first class letter these days is now 45 cents. No “forever” stamps in the drawer
