Ronald Acuna Jr

What does a Ronald Acuna Jr autograph cost?

From under a hundred dollars to the low thousands, one of the tighter ranges on this index. That narrowness is what a short career looks like: there has not yet been time for the scarce early items to separate from the ordinary ones.

What of his gets signed most often?

Cards, and very little else. His market runs to only five item types, the narrowest here, because a current player's signature arrives almost entirely through card manufacturers rather than through decades of shows and mail.

Why is his market so much smaller in variety than older players?

Compare him with Hank Aaron on this index, whose market spans eleven item types including balls, photographs, covers and cut signatures. That breadth accumulates over a lifetime of signing. A player still in his career has cards and not much else, and the rest arrives later or not at all.
