Circulation finds! I remember filling a Whitman folder of Jefferson nickels at that age and having a blast. These days, state quarters are probably the most fun you can have hunting from circulation.
Until recently I had a YN in the house. I found a foot to the small of the back combined with a forward extension of the leg usually was required to get him "started" in the morning.
Definitely a Redbook as Chris stated , and State Quarters as Charles 1997 stated as they are easy to find in circulation and have a wide variety of subjects . Does she like anything in particular like horses or flowers , as world coins have many different subjects and are quite cheap . Good luck , but definitely show some interest and don't force it . It's either there or it isn't .
might also get her a cent folder an some rolls of pennies to search thru to fill the holes in the folder..
That's how most of us old guys started . I recently bought a bag of wheaties mostly 30-40s and the 2 blue Whitmans , but I do throw in a semi key and the early dates just enough to keep her interested . This Christmas she got me in our $10 grab bag and heard she was super excited and asked her dad to take her to the local CS where she went in herself and bought me an Indian cent and a dateless Buffalo nickel . They are now priceless parts of coins that I never want sold and hope they stay in our family's future for a long time .
Start her out with what she wants to collect, the red book is a good starting place for images for her to look at ...
May sound weird, but the few I've kick started who had an interest, I bought each a five pound bag of world coins. They cost about $10 and had around 200 or so coins. It sparked their interest, and not so much for world coins, but in coins in general.
Great to hear! if a Redbook is in the near future, I have a few from several recent years that I've been wanting to get rid of (don't collect the Redbook here) and if this years' coinage isn't a must, let me know
