They're actually called mint marks rather than "symbols". There have been 8 different mint marks over the years.
Four mints are currently in operation:
P = Philadelphia Mint
D = Denver Mint (1906-present)
S = San Francisco Mint
W = West Point Mint.
In the past, there were:
CC = Carson City Mint
C = Charlotte Mint
D = Dahlonega Mint (1838-61)
O = New Orleans Mint
Most coins of the Philadelphia Mint earlier than 1980 are unmarked. Currently the Lincoln cent is the only coin that does not show a "P" when struck at the Philadelphia mint. --http://en.wikipedia.org/wiki/Mint_mark
The U.S. did not mint coins or print bills with that date. If you have a different year, a different denomination, or a bill issued by a private bank, please post a new question with those details.
You need to be more specific. There have not been any gold dollars released by the US Mint since 1889 for circulation (minus some minor collector editions before 1933) and there are no gold dollars dated 1978 struck by the US Mint. Instead you either have a gold plated 1978 dollar coin (which would just be worth $1) or you have a dollar coin issued by a different country or private mint.
It doesn't. The US Mint only makes coins. Paper currency is printed by the Bureau of Engraving and Printing which is totally separate from the US Mint. The production process is fairly complex, so it may be better to visit the BEP's site moneyfactory (dot) gov which has extensive written and video information about how America's paper money is made.
There's never been an E mint mark on US coins. Please check again - if there's a mint mark under the date it will be either D or S.
The US never minted a $2 coin. But they did mint quarter eagles ($2.5)
symbols of liberty
No-one created circuit symbols; they evolved over time. And, in fact, different countries use different standards for their symbols so US standard symbols, for example, are different from European standards.
Other US symbols have been produced by the US itself, but the Statue of Liberty was a gift from the nation of France.
Different societies have different reasons for having symbols, hence, the symbols are different. Tne symbols would be different, anyway, as different societies speak different languages, for the most part.

Different symbols were introduced by different people.
Which of these were found on the first coins issued by the U.S. mint?
You can buy directly from the US Mint, not the indivdual mint locations.
A number by itself is meaningless. Symbols and labels add meaning in math. Symbols in math are used to represent different operations, and/or add descriptions. There are many different symbols each which have their own purpose. Some symbols have different purposes in different types of math.
The 50 State Quarters Program were quarters released by the U.S. Mint every ten weeks, or five each year. It ran from 1999 through 2008. Each quarter's reverse commemorated one of the 50 states with a design emblematic of its unique history, traditions and symbols.
Mint marks were placed in different locations on each different coin series.
There aren't any collectible varieties, only different mint marks as on all Lincoln cents:No mint mark = PhiladelphiaD = DenverS = San Francisco (proof coins only)
