Personal inscriptions like "Good luck Mike" could sell for less than $400. A rarely signed full-name signature "Mickey Charles Mantle" will break the $2,000 price mark as it did in a May 5, 2007, live eBay auction, when it sold for $2,390.

Along with condition, the type of authenticity that accompanies the signature will dictate the price. Mickey Mantle was under contract with the Upper-Deck company before he passed away. Baseballs that have the Upper-Deck hologram could sell in the $1,000-$1,500 price range. And signatures that have not been authenticated could sell at half the market value or less.

That answer is really up to market conditions as well as what one individual will pay for a certain item. First things first, buy SCD (Sports Collectors Digest) as well as other Hobby Publications. Familiarize yourself with the price guidews listed for the particular player. Furthermore, if you have vintage material i.e. ball or picture signed in the 40's 50's etc...that will determine a premium for it...as well as condition. Remember, find out the provenance of the autograph.........if the seller doesn't know it or is very evaisive BUYER BEWARE. The hobby was built with the trust of seller buyer relationships.

Factor one. How was the signture(s) acquired? If you witnessed the signing then you know for sure that it is an authentic hand signed signature. If you found the Item in a box, or at a garage sale for example then there is a chance that it is not authentic, and can also be a facsimile signature.

Before you spend money on having the signatures authenticated be sure that they are not facsimile signatures. A lot of people mistaken facsimile signatures as authentic. Facsimile signatures are printed on, as opposed to authentic hand signed signatures. If the signatures are signed with a felt pen for example, the ink will tend to be heavier at points where the pen started, stopped or slowed while signing. Lighter, thinner, or less dense when the pen is quickened or coming off the item. With facsimile signatures the ink will trend to be more uniform, or the same density throughout.

Factor two. Authenticity. An autographed baseball that is not authenticated by a creditable company could sell at half the price or less than one that is. Two of the top, and most trusted authenticators are PSA/DNA, and James Spence Authentic (JSA). Collectors will pay more for signatures authenticated by either one. It may sound odd but in some cases PSA/DNA, and JSA authenticated signatures may sell higher than a Letter of authenticity from an unknown or less trusted authenticator that witnessed the signing even though PSA/DNA, and JSA did not. It's just a matter of collectors trust, and collectors will pay more for it.

Factor three Condition. As with all collectibles this could be the most important factor of all providing that the signatures are authentic. The condition of the Item signed, as well as the signatures. The signature should be strong, and bold, as opposed to faded and hard to see. In the case of a baseball Blue ball point pen would be most preferred over sharpie which tends to fade quicker or bleed on a baseball. An educated collector will pay less for a sharpie signed baseball, if at all. Sharpie would be most preferred on a bat, or Photo.

Factor Four The type of baseball that the signatures are signed on, as well as where the signatures were signed could also determine the price. An official baseball that was used during the players career will sell at a higher price. This can be determined by the stamp of the league president on the baseball. The manager or, and team star would be most desirable on the sweet spot. Collectors will also pay a premium for inscriptions such as "500 Home runs," and pay less for personal inscriptions like "Good Luck Mary."

Price guides are based on average prices of recently sold, and closed auctions. Prices may vary based on condition, and the type of authenticity that accompanies the baseball. Prices may also vary on team signed baseballs based on the amount of signatures, and key signatures acquired. The more complete the baseball with key signatures the more valuable.

You may find prices on single signed baseballs, as well as team signed baseballs on my website. The team signed baseball price guide includes a list of key players as well as links to full team rosters year by year. I will provide a link on this page for your convenience.

A Mickey Mantle signed 8 x 10 photo sells for about $150.-$300. Price will vary based on condition, and the type of authenticity that accompanies the signature. Photo composition, and appeal will effect the price as well. Part of the value will be determined by how well the photo displays the signature. The type of ink used, and how it stands out in contrast to the photograph will also effect the price. Sharpie would be most preferred for a photo. Larger and more desired pictures could sell for more.

Mickey Mantle signed a lot of Autographs. One of the most sought after signatures, there are also a lot of fakes on the market. The numbers are alarming. This is why to get top dollar for an autograph it should be properly authenticated. Signatures that are not properly authenticated could sell at half the market value or less.

A 1989 Ken Griffey Jr. rookie signed baseball card is worth on average $30.-$40. Prices may vary based on condition, and the type of authenticity that accompanies the signature.

Collectible items could add value to the price of a signature but not always. As in the case of a baseball card, generally collectors of baseball cards would rather have a baseball card without the signature. The signature would be considered as a flaw in the condition of the card and will lower the value.

A collector of signatures will not always pay extra for the "collectible" baseball card. The autograph collectors main concern is displaying the signature. This is why it is not a good idea to have an expensive baseball card signed. You could devalue the price of the card, and get less for it.

Common flaws with baseball cards include: rounded edges, creases, off centered, and faded color. Any or all flaws will devalue the card significantly.
