A 1990 Leaf Bryan Harvey baseball card 116 has a book value of about .40 cents in near/mint -mint condition. Professionally graded cards will sell for more. Condition is important.
Common flaws with baseball cards include: rounded edges, creases, off centered, and faded color. Any or all flaws will devalue the card significantly.
If it comes right from WGA (Wayne Gretzky Authentics) it will be worth around $1000-$1400. If it comes from a different source then the value drops greatly. If it has no authenticity papers at all it is next to wortless as you can't prove it is authentic.
This sounds like a very nice bit of unique signed baseball memorabilia, particularly because it includes a substantial element of provenance: the who, what, when and where of its history. Genuine autographs of Babe Ruth and Lou Gehrig are highly sought by collectors and potentially very valuable. Presuming authenticity, values can range dramatically -- one can presume at minimum, $1,000 to as much as $3,000 for the lot. Key factors above and beyond authenticity are: the placement and clarity of the signatures (the bigger and bolder, the better), and the all-important overall condition and aesthetic of the pieces and potential for display. With autographs, a picture is truly worth the proverbial thousand words, and can save alotta time in the authentication, appraisal, and selling process.
A Curt Schilling signed Poster would be compatible in value with a 8 x 10 photo which is worth about $60.-$100. Larger and more desired photos could sell for more. The quality of the paper used, and the condition of the poster will be a major factor in value. Poster paper could easily rip, as opposed to a photograph and keep the value down. The overall display of the signature will dictate the bulk of the value. A "Bloody Sock" poster might have added value. Value is based on average prices of recently closed auctions. Prices may vary based on condition, and the type of authenticity that accompanies the signature. Signatures that have not been properly authenticated could sell at half the market value or less. Add for inscriptions. Collectors will pay more for inscriptions such as "HOF" and pay less for personalized inscriptions like "Good Luck Chuck" Signatures authenticated by Steiner sports, or MLB with attached hologram sell at the higher price.
A Beckett guide published in 1998 estimates the value of a 1936 World Series program in "excellent" condition at $150. to $175. Mint/near mint at $400. I dont know if Beckett has updated the '98 guide. Ebay would be another source for recent sale prices. A 1936 New York Yankees World Series program played at Yankee Stadium is worth about $375.-$400. in excellent - near/mint condition. A 1936 New York Giants World Series program played at The Polo Grounds is worth $200.-$400. As stated above eBay is a great place to find current value. Price guides base their values on closed auctions as well, but if printed on a yearly basis could be out of date. On eBay you will see what collectors are paying, now, and you can also take note of the condition, as compared to yours. I did not find an auction for a 1936 program but In a recent eBay auction a 1937 WORLD SERIES - NEW YORK YANKEES (4) vs GIANTS (1) - GAME 1 at YANKEE STADIUM in less than excellent condition sold for $215. As with all collectibles, condition is the most important factor of all providing that the item is authentic. With programs/scorecards the slightest flaws will bring the price down significantly. An exceptional mint condition scorecard could sell for more.
Common flaws would be staining, foxing (yellowing), fading, creases, rips, loose pages, cracked binding, and writing on the cover. Un-scored programs will generally sell at a higher price than a scored program but sometimes it doesn't effect value. The over all condition, and how well the cover displays will.
The value on a "scored" program as opposed to a un-scored program can vary depending on the game, and collectors preference. In general I would say an un-scored program will sell at a higher price. Some collectors do not mind scored programs, or might prefer it scored. A game in note that might sell at a higher price "scored" would be Don Larsens perfect game in the World Series. I will leave a link below for more information on scorecards, and publications.
