How to collect a series

Most collectors use a folder or album with one hole per date and mint mark, and fill it from change and bank rolls. Start with a recent series where most coins are easy to find, then move to older ones. Check each coin’s mint mark and condition before you place it. The MintPriced app has series slots for US series, so you can see what is still missing.

For full date-by-date data, NGC’s free Coin Explorer and the U.S. Mint’s history pages are good starting points.
