How much does the year/scarcity of the card affect the the value?
Obviosuly a signed T206 or ’33 Goudey will always bring a premium over cards from recent eras unless you have a Clemente or Munson for instance.
How much does the "grade/eye appeal" of the card itself affect value? Unless the auto is deemed “rare” then eye appeal counts for a lot in my opinion.
Does the type of writing utensil have any affect on value, i.e. blue vs black, pen vs marker?
If the auto is clean and readable then I do not think there is a big difference.
Is there anything else that I should know or be intrigued by? “the meaning of life!”
Lastly, if you had to put a range of value of the card, what would it be?
One of these unslabbed just sold on Ebay for $25. Item #171730682455. Yours is slabbed so there is that premium but your card is also very beat up around the edges so……my guess would be $65 tops and a low of maybe $40.
