The Lineberger Standard
Memorabilia, reimagined as heirloom.
We believe a great piece of sports memorabilia should tell a story, pass a handshake across decades, and feel unmistakably at home on the finest shelf in the house. That is the quiet promise behind every item in our collection.
Authenticated
Every signed piece is paired with third-party authentication from JSA or Beckett.
Museum-Grade
Condition, provenance and presentation refined to the standard of a private gallery.
Curated Personally
Greg Lineberger hand-selects each acquisition. No mass-market marketplace — just taste.
