Need To Start New Collection (I Am A Kid) So Any Advice?

Don't know if you use Albums nor if you try to use all one brand. You mentioned purchasing them on ebay. Not sure if you can find a coin store, hobby store that carries coin Albums in your area. If so you may find it cheaper to purchase them there. At some coin shops they take in Albums of coins from people. They then sell off the coins separately. This means they have used Albums for sale also. At some places they sell them for a fraction of the original cost. Then too the brand may depend on the area you live. In the West, Dansco's are more popular due to being made there. Whitman's are really more common in the MidWest since they too are in the MidWest. Littleton is sort of popular in the East due to being made there but still not to popular. Others are either more expensive or just not to popular.
I'm a Whitman person myself. I prefer the look of a blud background for Coins. They stand out more. Danso's color makes it difficult to really see a Copper coin well.
One of the nicer things about Whitman is the size of the Album Covers. You can add many more pages in them. For example I can put two sets of Mercury dimes in one cover. Or make an Album of Liberty Head, Mercury Head and Roosevelt dimes all in one album. I use the blank pages for that, with the add on sheets of press on numbers/letters from Whitman too.
Regardless you have a fantastic great start in coins.

Mercury dimes are one of my favorites as well. Concentrate on better coins at bargain basement prices. You can often times find rare or nice condition Mercury dimes for around bullion price. Also talk to your local coin dealer. Most of us like educating young folks in our business. I started collecting coins when I was 9 and it has made quite a difference in my life because of it. I have built up some nice collections over the years simply by being in the business. Whenever a young person comes into my store and wants to learn about coins I give them an old RedBook and a long speech explaining what I did as a kid and the benefits of being an informed consumer. Additionally I treat new collectors extra well when it comes to selling some of my inventory. I was treated very well as a child from my local coin shop owner and I feel it is my duty and obligation to do the same for the next generation. Congratulations on being MATURE enough to make a LIFETIME investment that pays dividends in both emotional and financial ways. Best wishes on your efforts to build your sets (and don't be put off by Morgan silver dollars price either). Sincerely, John Leckrone

I think that the Mercury dimes are your best bet. They can be very affordable in the lower circulated grades (1-2 dollars) and they are also nominally affordable in the higher ms grades fir the later dates (1940s) about 10-15 dollars.

Disregarding the keys, this set is very doable. The 1921 coins can be had for less than 100 in g vg. The 16 d will only be a stopper until you save up enough to get it and it is widely available!

Good luck!
