If you are referring to a large coin bearing a picture of Miss Liberty walking, you have a bullion piece sold for its metal content, and worth about $17 at current prices. The denomination of these pieces is artificial because they're sold as precious-metal investments, not for spending.
OTOH if you're using the generic term "silver dollar" to refer to one of the small dollar coins carrying a picture of Sacagawea on the front, it's made of copper and manganese, and is worth face value only.
So many were made that most uncirculated 2006 US nickels retail for less than 50 cents. Very high quality strikes (MS64 and above) can retail for $2 to $15, though.
It depends on where and how you found it, and its mint mark. 2006 Sacajawea "golden" (actually brass) dollars were minted only for collectors but some have ended up in circulation. If you got it in change, it's only worth face value. If you have an uncirculated P-mint coin in its original package it might retail for $2 to $12 depending on quality. If you have an uncirculated D-mint coin the range would be $4 to $18.
It's a bullion coin sold for its silver content. As of 07/2008 that's around $17 but varies with the spot price of silver - check the financial section of a newspaper, or CNNMoney.com, for recent quotes.
Generally yes, very much so. Silver has fluctuated in value but has been in the $10 to $18 range during most of the period 2006-2008, so that makes a silver quarter worth at least 5 or 6 times its face value. Also, silver quarters are older so some of them are scarce enough to be worth even more as collector's items.
Still only 5 cents.
If you've got an uncirculated coin it is worth silver melt (it has 1 troy ounce of silver), about $32 at the time of writing (although silver spot changes dramatically). If you've got a proof issue (should be in a box with a capsule and should say "proof" on the COA included in the box) you've got a small premium over silver melt, about $50 for a coin in box with the COA included.
It is worth what 1 oz of silver is worth which at the time of writing is $27.59 but silver changes in prices very frequently.
Yes, it can be spent. To a collector, it might be worth a couple of dollars above face value.
Depending on which company is certifying that grade, it can be worth anywhere from $45 to $125
Probably around $22-25 USD.
A nice uncirculated one might retail for $1.25 to $1.50. Any of the billions that are already in circulation will be worth exactly $1.
The 2006 Jefferson nickel has a value that varies depending on its condition. If you found it in change, it has no added value. An uncirculated one could be worth 35 to 50 cents while a proof coin would be over a dollar.
4 Different kinds were struck in 2006: 1. 2006 Uncirculated no mint mark 2. 2006W Burnished uncirculated 3. 2006W Proof 4. 2006P Reverse Proof
I is worth nothing. A dollar store probably made it for a joke.
No. They all are dated 2006.
It is worth $5.00
One is still worth exactly $100, because it's not rare or old enough to be worth more.
