There are two issues with this question.
(Actually, if you mean a recent... that is, minted in the last 15 years... "gold" dollar coin, they aren't really gold, and it's worth exactly one dollar. If it's in mint condition... this does not mean "it looks really nice", but literally exactly as it came from the mint... it might be worth slightly more to a collector.)
No 1977 Ike dollars contain silver. On average, it's worth about $2.
It's an extremely common date, still worth one dollar.
The value of an Ike dollar, also known as the Eisenhower dollar, varies depending on its condition and mint mark. Generally, circulated coins are worth face value, but uncirculated examples and collectible varieties can be worth more to collectors.
It's still worth one dollar.
It doesn't matter what the DATE or MINTMARK is, coins made for general circulation do not have any silver and are only face value. Only some of the "S" mintmarked coins from 71 to 76 are 40% silver.
That's Eisenhower, not "eisenhouer", and if it's Ike's picture you have a $1 coin, not a half dollar; if you have a half dollar it's JFK's picture, not President Eisenhower.Please determine which one you have and post a new question including the coin's date.
None of the Eisenhower's released for circulation have silver. For 1971 & 1972 only, all S mint marked coins are 40% silver. From 1973 to 1976 the S mint marked coins in the standard proof sets are clad coins, the 40% silver Ike's were sold separately but they were included in the bicentennial 3-piece silver sets. No silver Ike's were struck in 1977 or 1978.
Unless they're uncirculated or proof coins, Ike dollars are only worth face value to maybe $1.15 depending on how worn they are. BTW there were 26.5 million Ikes made in 1977 so it's not at all clear what you mean by "none minted".
1.5 inches, or 38.1 millimeters.
In general, Ike dollars are still worth one dollar.
None at all. No Eisenhower Dollars that were issued for circulation (1971-1978) contain silver.
Not much I'm afraid, unless it has an "S" mintmark and is 40% silver and worth about $6.50-ish in silver content. Collector demand for Eisenhower dollars are rather low and many banks still have non-silver Ike dollars in stock if you ask for them.
