You can type in a good description of the coin, it's likely that someone out there has another one just like it.  Otherwise, take it to a coin shop.

Since you don't give any mint marks or any comments about condition, as well as only describing one side of the coin, this is hard to answer, but I'll do my best. \n\nFIRST COIN: I can't answer this without knowing what's on the back and the size of the coin. There were several coins from this period that looked like this - half dimes, quarters, dollars, and $10 dollar coins. E-mail me with details and dimensions, and I'll find out for you.\n\n\nSECOND COIN: CONGRATULATIONS!!!! You have a fairly rare coin that is worth, at the poorest grade, $85. If the coin is in pretty good condition, it could be worth thousands ($4000 sound OK?). I HIGHLY recommend you take this coin to a reputable dealer to have it appraised and placed in a protective case. You may also want to have it insured.

look it up in a coin magazine\n\nnever trust coin dealers\n\nthey apraise low then resale for a much higher apraisal value

Do you have a photo? You also may want to connect with a coin dealer for more accurate information.

There should be a security strip....if you hold it up to the light you can see that it says 100   ( or whatever denomination you are checking)  There should also be a watermark....it should be a smaller version of the protrait of the president (franklin for the 100 although he wasn't a president)  that can also only be seen if you hold it up to the light....the watermark will not distort so if you find one with a funky watermark it's a fake....look at the lines that are close together and the small lettering....those are very hard to replicate without blurring or distorting....detail is the key.....one of the numbers in the corners (don't remember which one)should feel raised and change colors as you look at it at different angles.....there should be red and blue fibers visible....that's because money is not printed on paper but some form of cloth paper....You can try to carefully tear the bill....a real one will stretch a tiny bit where as a fake one on regular paper will rip...you can also feel the difference in paper.....You can try and buy one of those pens that banks use that change colors....you can try looking at it under a black light...a fake will light up like a flashlight....or you can wash it in the washing machine....regular paper will fade and fall apart in the first washing where as you would need to repeatedly wash real money until the appearance really changes..

Check eBay.  Lots of coins bought/sold there.

take it to a bank and have them check it. \n\n2.00 bills are older, so the watermark may not exist, if they were made some time ago.\n\nGenerally the feel of a counterfeit bill is smoother than a true bill. \n\nThe Bank will know. \nGood luck.

If it's a proof, or in mint condition, or is a "mistake" (ie, double-struck, half-struck, etc) then it would be valuable.  If its a regular circulated coin its only going to be worth face value.  To be sure, try taking it to a coin collector/dealer and asking them to tell you what its worth.  Or find a pricing guide in your local library (the official pricing guide is called a red book).

A "genuine" two headed coin has never been proven found in circulation, Tens-of-thousands of faked double-headed and double-tailed (and other similar mismatched concoctions) have been made from genuine coins altered by machine shops after the coins left the Mint.  These have been offered for sale by novelty concerns like magic shops and through ads in comic books for decades for prices starting at about $3 or $4 for cents up to about $8 or $10 on half dollar coins.  Many of these get into circulation quite innocently and are later found by unsuspecting collectors who think they found rare Mint errors!  \n    To read more about the specifics of these alterations go here:\n\nhttp://www.pcgs.com/articles/article_view.chtml?universeid=313&artid=799&universeid=81&universeid=313

Have an apraiser come out and take a look at it.  I know that is probably not the answer that you were looking for, but I wouldn't trust someone who has not seen it to know what it's worth.

Go on ebay and type the year and denomination of the bill\n\nthat will give you some kind of an idea.

Look for any of these marks:\n\nSilver- Ster, Sterling, 800, 900, 925\n\nGold- 585, 9K, 10K, 12K, 14K, ect.\n\nIf they are unmarked:\n\nDo not acid test, especially silver! Take them to a Jeweler. Most of the time, they will tell you for free.

Your best bet is to find a coin dealer in your area.  You can check out approximate values by looking at what the coin and silver certifates are selling for on ebay, or at one of the online price guides.  Good luck!

These are called 'Grease die errors'.  Grease got between the die and the coin and prevented some part of the design to be stamped on the coin.  This is very common in the Delaware coin, where it reads "THE FIRST STAT".  I have a two New Jersey coins with grease die errors, and they are worth between 25 cents and $5 each.  Search for them on ebay yourself.  There are always people trying to sell these things for hundreds of dollars, but no one bids on them.  The ones that sell all go for less than $5.

The value is about .99 cents - $2.00 depending on what little letter is stamped on the coin is it a P or D or S.\nAnd what coloration does it have look at the site below for a list of values (this guy seems to be selling them though so you should check Ebay to see what they're going for).\nI didn't see the other guys answer checking with his site would probable be best.

The 1990 $100 is only worth $100 but the penny should be worth a lot. Go to a coin dealer and have it appraised
