They're not an official Mint product. Private companies create these from normal proof coins and market them as "keepsakes".
The bad news is that the plating means they're considered to be altered coins which destroyed any collector value they may have had.
IF the coins were special "prestige" proofs, you could at least recover the value of the underlying silver. But if they're standard clad composition, they've lost all extra value. The coins would have to be weighed to determine which type you have, because the plating covers up the edge which would show silver for a Prestige Proof and copper for a standard proof.
It most likely is gold plated, gold plating adds really no value to the coin and like any other 1999 nickel, it is worth 5 cents.
The US has never minted gold quarters. A private company took genuine proof quarters and plated them with a thin layer of gold. Unfortunately that means they're altered coins and have lost any numismatic value they had as proofs.
It is only gold plated. Since it is gold plated it is an altered coin and is worth 50 cents.
The gold plating adds nothing to the value of 25 cents, unless you find someone that wants it, it's a quarter.
Not gold, and not proof. All proof coins dated 2000 were minted in San Francisco, and the US never struck gold quarters. You almost certainly have a normal Philadelphia quarter that's been plated with a thin layer of gold. The plating makes it an altered coin with no added value.

All you can get it depends on who wants it
It's just a state quarter that has been gold plated and it has no collectible value at all, unless you find someone that wants it.
It is only gold plated which adds no extra value. Since it is a gold plated coin it is considered altered and is worth face value.
The 2011 50 dollar gold proof is pure 14mm 24k .9999 gold
The value of gold cufflinks would depend on the weight and purity of the gold used. Gold plated cufflinks would have a lower intrinsic value compared to solid gold. The Indian Head cents, if gold plated, would add a numismatic value depending on their condition and rarity. It is recommended to have a professional appraiser assess the items for an accurate valuation.
The value of gold plated rings depends on the price of gold and the rating of the gold karats at the time you are purchasing them. I would suggest comparing prices in several stores.

Anything with gold content has some value.
Very little. Plated gold is unbelievably thin and gold is valued by weight.
I saw on Ebay that a single gold plated tile was running about $5.00 (US).
