US Mint Official First Day Coin Covers

Are these US Mint Official First Day Coin Covers actually First Strikes? Do they generally contain Registry quality business strike gems? Thanks for your help.

Thanks again ellewood for your response. I've never seen an FDC, so I never quite understood the appeal.
I'm glad I saved my money.
That is from the US Mint.
Nothing comes close in an official certification than this.. NOTHING ..
PCGS is missing a huge market and it will show up soon in the Quarterly.
