The US Bicentennial Silver Uncirculated Set in the red envelope with white lettering was the standard packaging for the three-piece coin set.
In October 1976, the Mint introduced new "gift packaging" for the three-piece set in an effort to mark the year-end holidays and the end of the US bicentennial year (and, of course, to boost sales of the set). The new package was a white envelope with crimson (red) lettering and a view of Independence Hall in Philadelphia. The packaging was used by the Mint for orders received between October 1 and December 31, 1976. As the ordering period for the coin set in standard red envelope packaging was much longer, the red envelope sets are more commonly encountered vs. the white envelope sets. The price for the set (either package) in 1976 was $9.00.

There is another envelope as well, some apparently very few, came in a white envelope of the same style as the red one.
I haven't seen such an envelope from the US Mint - I'd enjoy seeing one. There was a plain white envelope with lettering the Mint used in 1975 and 1976 for the 12-coin P and D US Mint Uncirculated Set which included the three bicentennial coins as well as the one cent, five cents and ten cent coins, but the coins in those sets were struck on base metal planchets, not 40% silver ones.

All the coins were struck in 1975.
This is not accurate. The Mint struck the silver bicentennial coins in 1975 and 1976; its last mintage of the 40% silver coins took place in June 1976.
Quote:
... the legislation didn't just authorize the 15 million coins to be made, it REQUIRED them to all be struck by the end of the year.
The legislation for the bicentennial coins specified 45 million silver-clad coins were to be struck. The legislation included a provision that allowed the Secretary of the Treasury to strike an additional 15 million silver-clad coins if the public demand for them merited. Such demand did not materialize and the Mint struck 45 million coins (15 million of each denomination; 11 million uncirculated and 4 million proof). Also, the legislation specified the issue period for the coins to be July 4, 1975 to January 1, 1977.
