Yes, as said well above, the
RedBook is a key reference book. Many are vocal about the prices being much too high, but can be used for comparisons. I try to buy a
RedBook every couple of years . I have over 40 of them for price comparisons and such.
the Redbook~~ YES! The
ANA grading guide should be your next book! These 2 will save you a lot of pain and money over the years! Will repay their cost many times over. Then when you decide your main interest, reference books in the area.
This forum, and other coin forums, are archives of knowledge, photos, discussions of scams, rarities, grading practice, etc. Many coin sites have individualized reference of cents, halves, dollars, etc. Google can readily find the ones you don't see in the forum postings. Sometimes new members don't go far back in postings, but it is well worth the time. I've been in coins a long time and I learn many new things every week or day. Nice meeting you
