I have four baseball cads that came out of Kelloggs Corn Flakes. The front of the cards change pictures when you turn them. On the back is all of the stats and information. There were only 15 of these cards made. Billy Williams 9 of 15, Harmon Killebrew 6 of 15, Don Baylor 14 of 15, and Willie Mays3 of 15. Does any one think these are worth any money. Or any suggestions on where I can find out. Thank You

These cards are likely from the late 1970's. Kelloggs made cards that I have heard of from 1972 or so up until 1979 or so. They are worth most still sealed in opened packs, but in top condition even opened, the Willie Mays may be worth like $10-$20 is my guess. You can find out more on Ebay if you want, or post about it at a card site (I have one in my signature link which I own and operate). Type Kelloggs Willie Mays in Ebay, I am sure you will find something. Hope you read this because this will help.
