Lot of 4 vintage 1950s miniature mugs / shot glasses / toothpick holders

Lot of 4 vintage 1950s miniature mugs / shot glasses / toothpick holders the 2 with pinkish cranberry lower halves are definitely Federal Glass, from the 1950s, as they have the F (within a shield) stamped on the base...they measure approximately 1 7/8" H they are in MINT condition- no issues, nice glass quality the 2 other glasses (no base stamp), might be Federal Glass, or a contemporary competitor, and probably date to the 1950s or 60s...these measure approximately 2" H one glass is clear, but the one on the right (in pic 1) has a decidedly grey hue to it...these mini mugs come in a bunch of different shades, but i've never seen one quite like this before...side-by-side you can definitely notice a color difference with the clear glass one the gray one is in about mint condition- some very light lip roughness (believed to be in-manufacture) the clear is in very good condition, but does have a very small ping to the inside lip edge, you can just feel with a fingernail...there appears to be a line you can't feel at all extending from it (last pic) 4 cool little mini mugs! smoke-free environment same day / next day shipping cl
