The mintage is unknown.
What you have is most likely a "lamination error". Current US dimes, quarters, and half dollars have two outer layers of cupronickel cladding* bonded to a copper core. Blanks for the coins are punched out of large rolls of metal stock. Sometimes the ends of the rolls aren't properly clad and one or both sides may be missing from the copper core.
* "Plating" is normally a thin coat of metal applied electrically or chemically in a liquid bath. Cladding for coins is much thicker and is bonded mechanically.
Contact the company that you ordered them from. But if you are only missing the 2008 quarters, they haven't been minted yet, so the merchandiser can't damage them yet.

None. It is one of the few years that has no quarters that were minted. The Standing Liberty Quarter stopped being minted in 1930 and the familiar Washington quarter wouldn't be minted until 1932.
Silver quarters were minted from 1796 to 1964. Starting in 1965, quarters were made of a copper-nickel alloy.
No specific states had quarters minted in 1796. In 1796, the only quarter issued was the Quarter Dollar Draped Bust Small Eagle. The "States" series of quarters were not minted until 1999 and ran until 2008.
Quarters minted after 1965 do not contain silver. Only pre-1965 were struck with a certain percent of sliver.
