buy books first. how much money you want to spend on coins ? there are collectors that save up for a better grade coins or collectors that like cheap coins and lower grades.
I asked myself the same question when I started collecting for the second time. So many choices and price ranges to choose from. I decided to focus on Proof coins from 1950 on because I was born in 1951. I collect them in both brilliant and cameo...the cameos are all graded in slabs and the brilliants are all in Whitman plastic mint set holders. This is a lifetime effort for me as the earlier coins are not only difficult to find in cameo, but also rather spendy. I manage to buy several nice ones a year, so I,m down to around 15 missing cameos...I have all the brilliants though. From 1990 onward I leave them in the original mint holders because they seem to be fairly inert sleeves. Before 1990 coins are in the slabs and Whitman plastic holders because of terrible Mint packaging of the time. Hopefully, I can complete the full set before judgement day and pass them on.
I too started collecting young and then went through a long period of not collecting until after a divorce. At that time I got into building modern registry sets and buying rolls of small cents. I probably spent too much money on rolls before realizing I was coming out on the short end; I did enjoy searching and did find a number of semi key IHC and Lincolns. A few years ago I decided to retire early and purchase a second home before officially retiring. I needed money quickly so I ended up selling most of my collection at a significant loss (if I would have sold the coins at auctions or eBay over a longer period of time I probably would have fared much better). However, I have no regrets since I'm now retired and live where I bought the second home. I have jump started my collecting once again but in a different direction. I have more interest in building a nice type set, learning everything I can about each issue. Instead of dealing with a bulky collection of more common coins, I'm much happier with quality over quantity.
I also enjoy building my 70/70 type set slowly but surely. I learn a great deal from this forum, so I don't make so many mistakes along the way.
Sometimes the kick in the butt of a divorce - mine was after twenty years of marriage - ends up being a blessing in disguise in the sense that one gets to start over, all fresh and with a set of new eyes, and not a small part of this is facilitated by the fact that all the old (physical, at least) baggage has been left behind.
Go to the ANA's website: www.money.org and look up coin clubs by state. That will get you started and be a great help.
@SilverMike "The one thing I wish I had done was spent more time at the beginning looking and less time buying." This applies to women as well...good luck collecting.
If it for storage, the small zip lock bags they have in most Walmarts. 100 1x1 , 1x2, 2x3 inch bags were selling for $1-$2 per hundred, and if sealed they have a high protection ratio. If it is for display and handling, the hard special size hard plastic shells that snap together. From coin supplies dealers. Some people new to coins spend more money on the albums and supplies than coins.
Try JP's Corner - nice selection of magnifiers and practically anything else a coin enthusiast might need - lower prices than Az or eB
I like the suggestion of the DANSCO 7070 type set. But just get average grade coins in the process. You'll get an good overview of US coinage and in the process you might discover something that you are attracted to and decide to collect the entire series.
Want to start collecting again Then bloody well do it. Don't entertain us with the wherefore and why, just basted do it.......
