Mordecai Brown was a Major League Baseball player in the early 1900s and there are several of his cards still in existence, so the value would depend on the year and condition of each card. For example, 1909 American Caramel goes for $440.
The entire four card "Record Breakers" set is only worth $4 to $5. Therefore, an individual card from the set is worth between 50 cents and $1.
The value of the card depends on the player, the manufacturer, the year the of the card and the condition of the card.
A 1981 Topps Bobby Brown card number 418 has a book value of about .20 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.
The value depends on which card it is, and what you mean by fake autograph. If you mean a facsimile autograph, a copy of Babe Ruth's signature that is part of the printing of the card, then the value of the card will rely on the year, and the set the card is from. If you mean someone wrote on the card "Babe Ruth" then the value of the card will be drastically lowered in value, if any value at all.
Not "THE BLACK CARD" probably a silly Visa card
