No discrimination in this thread, if it is copper you can post it even if minted yesterday.   Lots of die polish on the 64.
 

Your coin is not one of the so called SMS coins, just a normal brilliant proof.

Look like $1 Sacagawea coins from early 2000's. Worth something, but I don't believe there worth over $10 for all 3. Do you have bicentennial quarters from 1976? Those can be pricey if you have a rare one. Do your research, and be wary asking a local coin shop, they might low ball you and not mention certain rare coins to get them from you cheap. Keep trying, you might have a Cash Coin worth something.

Any copper is good. PCGS gave this one  Genuine UNC Details (92 - Cleaned). 
 

Welcome to the NGC chat board.
   No. Unfortunately, the coin has been scratched by a roll wrapping machine.  

Hello and welcome to the forum. Looks like damage from a coin rolling machine. Your coin was at the end of the roll when wrapped.

Welcome to the boards!  Agree with the above (1990).  You can take it to the bank (literally, that's what you should do).

Agree that your coin is dated 1990, the lower leg of the second nine has been obliviated from some type of damage.   Your grandfather may have found it interesting and that is why he kept it, but it has no numismatic value beyond the face value of 5 cents.

Welcome to the NGC chat board.
   Your coin is a 1990-P Jefferson nickel with damage affecting the date numerals. It has no collector value. The earliest Jefferson nickels were struck in and are dated 1938.  A nickel dated 1900 would be of the Liberty head type dated 1883-1912 and would look like this 1897:


 

Thank you, those are much better, but alas as greenstang wrote these new photos prove that the coin has indeed been plated in the past.

Welcome to the forum, sadly your photos are woefully inadequate for anyone to give you an in depth evaluation.   But what I can see from them and using your description, is a coin that has been plated in the past as a novelty item.   That takes all the numismatic value out of the equation and leaves you with a value of approximately 3 cents for the copper metal in the coin.
There is no way to opine on values you have seen online without knowing what and where you have been getting your valuations.   However, it is not uncommon on sites like etsy, ebay, FB and others to have sellers that post outlandish prices for common and even damaged coins.   Some are pure scammers out to land a big fish, some are just completely clueless and do not attempt to actually find out what they have or what it is really worth.
As already noted above the 1930 cent produced in Philidelphia is common and does not command a high value unless in exceptional condition.   This surprises many non collectors as many equate something that is nearly 100 years old as being valuable.   In numismatics the age of a coin is only one part of valuation, condition of the coin, rarity of the date, and survivability of the date all play a part in how valuable any coin is.
I will leave you with this screen shot of a 1930 cent that was graded by PCGS (in case you don't know PCGS is another firm like NGC) that sold for just $55.   That may seem like alot for a single coin but consider that the grade of MS65 is a high grade, and it would cost close to $50 to send a single coin in to be certified and graded by NGC.

Thank you, those are much better, but alas as greenstang wrote these new photos prove that the coin has indeed been plated in the past.
