First off

I collected coins as a kid and then spent them like a kid. But I came back to collecting a few years ago as an adult, and here is what I do, or have done.
I started out collecting by roll searching and putting everything into folders. When I began to find fewer and fewer upgrades from searching, I move everything to 2x2s, and put them in plastic sheets in binders. The nicer coins go into either airtites or snaptites. I then give away the folders to individuals like you.
You will want to buy yourself a loupe. Most people recommend a 10x. Personally tho, I have a 10x magnifying glass, a 30x loupe, and a USB microscope for my laptop which I also use to take photos with.
In my "Library" I have a copy of the
Red Book as well as the Blue book. A copy of "Strike it Rich with pocket change". Also both volumes of "
CherryPickers' Guide to rare die varities...". Next is a copy of the "
ANA Grading Standards". Finally, Whitman has a series of Guide Books for each denomination and series. Of those I have the ones for "Flying Eagle and
Indian Head cents", "Lincoln cents", "Buffalo and
Jefferson nickels", and the "Franklin and
Kennedy halves" guide books. I need the ones for "
Liberty nickels" and also "
Mercury dime".
Now looking at the folders you bought, keep in mind the following is just MY personal opinion or preferances.
The post 1965
Roosevelt dimes I don't collect. I have one 1964
Roosevelt dime I found in pocket change and that's it. I still haven't found a 2009 yet, but when I do, that will be kept. I don't care for the coin myself. I prefer the
Mercury dime.
The
State Quarters, I know won't be worth much if collected from circulation, but they were fun. I started collecting them when the Territory Quarters were coming out and found myself waiting with great anticipation until the next one came out. Most were pretty easy to get, but I did have to buy a few P mints 'cuz I live on the west coast and didn't want to wait for them to get here. I don't collect the
America the Beautiful Quarters tho. Kinda too much of a good thing deal. Perhaps closer to the end of the run.
Jefferson nickels 1962-1996. My circulating collection is from 1938-1959. From 1960 to Present I am collecting Proofs only, with the exception of the "Westward Journey" nickels and any with Full Steps.
Cents. I collect the Flying Eagle and
Indian Head cents, along with the
Lincoln Cent. You can get most of the
Lincoln Cent set from 1909 on, from roll searching and pocket change. As a matter of fact, I found my 1909 Lincoln roll searching. So If you are roll searching and collecting Lincoln cents, I suggest starting those from 1909. Then you'll have the Wheat, Memorial, Bicentennial, and Shield Lincoln cents.
The
Washington quarters I don't collect. Again, the coin just doesn't appeal to me. If I were to collect these it would be pre-1965 only and that's because of the silver content. Same for the
Roosevelt dime.

Do I just go to garage sales and shows and auctions until I amass enough of these elusive coins to call myself a collector?
Yes and coin dealers too. I think you can already call yourself a collector.
Quote:or do I go through
Kennedy halves until I get a lot of silver?
If you are a collector, it's not about the silver. It's about the coin. If you even remotely think you might collect these, this is where I would focus your attention. As you have discovered, roll searching is a good way to get a collection going. About a year or so ago I decided I better get on this collection, because the silver miners were hitting them hard. I hit it kinda hard too and at one point bought 5 boxes of halves at a time, thinking that I should still be able to get a circulating set from roll searching. Nope, could not do it. I went to my coin dealer and was able to trade for the last few I needed. So I still never paid more than face value. But that's been a little while and it's going to do nothing but get harder to do, because those silver miners are still there melting our hobby.

A box of these run $500, so you might want to start with just a few rolls.
