I know that I was a newbie once, and I certainly made my share of bonehead posts - and still do, I suppose - but it seems like we keep getting people on here who:
(a) think that nearly every coin they run across has to be some some sort of special strike, experimental finish, error, or variety, or
(b) think that they are right, and everyone else is wrong, and that they are more knowledgeable than people with many more years of experience than them, or
(c) think that, since no one agrees with them, then everyone besides them either has a huge ego that prevents them from admitting that they are wrong or don't know, or is out to destroy their dreams, or
(d) can not accept constructive criticism or correction without getting defensive, or
(e) have gone off their meds, or are over self-medicating, or
(f) lack basic social skills

First: the "poor man's doubled die" is a rip-off created by people who wanted to take advantage of collectors who wanted something special but could not afford a genuine '55 Doubled Die cent. It is an attempt to have someone spend money on what is, essentially, a damaged coin. Your coin looks to have that damage - either strike damage, or die deterioration damage, or both. It doesn't look like one of the known doubled dies for that year, but Variety Vista has identified ten different ones for that year and mint. If you want to compare your coin to them, the link for their site is HERE.

In my opinion, pretty much any Roosevelt dime made after about 1950 will need to grade MS67 and receive the Full Torch designation, in order to make it worth the money to have it graded. Most dimes minted after the mid 80's will need to grade a minimum of MS68. To be designated Full Torch, all horizontal and vertical lines on the torch must be complete, without breaks from damage or weak strike. Neither of the reverse pictures that you posted show a dime that would qualify for the full torch designation,(also my opinion). And, even though the pictures are not very clear, I don't think any of the coins shown would grade MS67 or higher. They would make really nice coins for a Roosevelt set album, though. In other words, if the coins were mine, I would not have any of them graded.

Keep in mind, also, that, with your scale only reading to one decimal place, your coin could weigh anywhere from 2.85 to 2.94 grams, and your scale would still read "2.9."
The weight is outside the tolerance for either type of planchet, so checking your scale for accuracy, as the previous posters have suggested, would be the first step.

Apparently, I misunderstood the meaning of your phrase, "....metal detector...geeeeeez !"

I believe I read somewhere that some of the old presses were sold for scrap, and ended up in China, where they were (and maybe still are) used to manufacture counterfeit coins. There is also one in use in Colorado at the Moonlight mint.

Are you saying that this "MS 70" can turn some coppers blue?

This particular seller, centsles, has been mentioned more than once over the years - here and ATS - as a seller of problem coins. He/she is best avoided.

Great giveaway! Merry Christmas! 

The 2013 Roosevelt looks like it has been subjected to intense heat.

I imagine all of these coins would be eligible for certification, although I think none of them would be worth the cost. All appear to be worth only face value.

In the case of your two coins, "FS" means two different things. As stated above by JKK and Coinbuf, the "FS" on the nickel refers to "full steps." And, as JT stated, the "FS" on the Lincoln refers to the variety, and stands for "Fivaz-Stanton," the names of the authors of the "Cherrypicker's Guide to Rare Die Varieties."

Hang on.
Don't let me, or anyone else, decide what you should collect. Just because strike damaged coins are not varieties does not mean that you can't keep them, if that is what you choose to do. They may never be worth more than face value, but some are quite interesting looking. Collect what you like.
