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.)
The plating makes it an altered coin, so it is worth face value only. Gold plated coins have no extra value since they are only gold plated and contain very very little gold.
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.
It is just gold plated. These are very common and worth a dollar. The amount of actual gold is very small and doesn't add any value.
$1. Gold plating adds just a tiny amount of gold and collectors view the coin as damaged. Such coins are common and only worth face value.
Eisenhower dollars aren't made of gold. They're copper and nickel and worth face value. If one is gold, it's only gold plated, and could be sold for a few dollars.
They are brass not gold. The value is right around $1.50 for uncirculated coins and face value for circulated coins.
it depends on how old it is...
No 1977 Ike dollars contain silver. On average, it's worth about $2.
It's an extremely common date, still worth one dollar.
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.
Roughly 100 Ike cents.
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.
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.
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.
