Unfortunately 5 different U.S. Mint issued sets have the bicentennial dual date 1776-1976. They were struck as Proof & Uncirculated in copper-nickel and 40% silver.
A 3-piece set is 40% silver with a value of about $25.00. The rest are $6.00.
It's the special bicentennial dollar, which was actually minted for two years, and is still worth one dollar.
Ten cents It's a common circulation coin. 568,760,000 were minted at Philadelphia (no mint mark) and 695,222,774 were minted at Denver (D mint mark)
If your coin has the dual dates 1776-1976 on it, it was minted as part of the celebration of the U.S. Bicentennial. You didn't specify its denomination but the only dual-dated coins issued were quarters, halves, and dollars. All were minted for circulation in enormous quantities, so if you have anything except a proof version with an S mint mark, it's likely to be only worth its face value.
Probably still one dollar. The only ones worth more are the silver or proof coins minted in San Francisco.
There were no US coins minted in 1776.

There's nothing called a "commerative" coin. There are COMMEMORATIVE coins, but an coin from 1985 is unlikely to commemorate any major bicentennial. Special coins were minted in 1976 for the 200th anniversary of independence, and others were minted in 1989 for the 200th anniversary of the Constitution.
Which country and what coin?

That really depends on the year the coin was minted and the condition of the coin.
There was no such coin minted in the USA in 1924.
What you presumably have is a James Buchanan presidential dollar coin. It was minted in 2010 and is worth one dollar.
The US mint did not start minting coins officially until 1793. What you have is likely a bicentennial coin with dual dates on the front 1776-1976, these coins were minted in 1976 and have no additional value beyond face value when taken from circulation.
