silver on the outside/ small gold coin inside
No, because old gold coins didn't contain any silver.
Yes
None that I know of. The idea behind having a different metal in the core of any coin is to increase the coin's structural integrity. Gold is quite soft and though valuable, would make a poor choice for any coin. You may be thinking of a so-called bimetallic coin. Many countries issue these coins, but they're made of brass and copper-nickel, not gold and silver. Examples are the Canadian $2 coin, the European €1 and €2 coins, and the British £2 coin.
Because they mostly have a collectible value.
It was a gold or silver coin
No silver or gold 1 dollar coins were struck in 1933
Not a meaningful question. Gold coins were made from gold and copper without any silver in them. Silver coins were made from silver and copper without any gold.
Other than coin dealers many jewelers buy gold and silver
The answer is yes to both. The outer layers of the coin are 80% silver / 20% copper and the core has essentially the reverse percentages, for an overall content of 40% silver / 60% copper.In average condition they sell for $2.50 - $3.00 based on the price of silver as of 11/2009
