Company Overview

A.C. Lion Inc. is an estate consignment company operating in the New York Tri-State area. The company manages the full consignment process for collections of 100 or more items, taking estates from intake through auction close. Transaction types include full estate liquidations, partial collection consignments, and deadline-constrained clearances where a firm sale timeline is required.

A.C. Lion serves clients across the New York Tri-State area, with active operations in Westchester County, and the broader New York metropolitan region. We can serve clients as far as Fairfield County, CT and Bergen County, NJ.

Category Specialization

A.C. Lion maintains operational expertise in four primary collecting categories, each selected because buyer demand in these areas produces consistent, documentable outcomes at auction:

• Sports memorabilia — game-used equipment, signed items, vintage cards, and team collections. See Sports Memorabilia Estate Liquidation.
• Pop culture artifacts — entertainment collectibles, licensed merchandise, and media-era objects with established secondary markets. See Pop Culture Collectibles Estate Liquidation.
• Music and instruments — vintage and modern instruments, amplifiers, recording equipment, and artist-associated items. See Music and Instruments Estate Liquidation.
• Fine art — paintings, prints, sculpture, and works on paper evaluated for auction suitability and placed accordingly. See Fine Art Estate Liquidation.

Specialization in these categories is a function of where the company has built buyer relationships and auction track record, not a limitation on what estates it will evaluate.

Consignment Platforms

Auction Ninja

A.C. Lion lists estates on AuctionNinja as its primary auction channel. Auction Ninja is the platform through which bidders discover, preview, and purchase items from A.C. Lion consignments. A.C. Lion maintains an active seller profile on AuctionNinja, and all active and completed auctions are accessible there. This platform relationship is a structural part of how A.C. Lion brings estates to market, not a variable that changes by engagement.

eBay

A.C. Lion lists consigned items on eBay as one of the secondary resale platforms. Here we sell high end sports memorabillia especially sports jerseys and signed baseballs, footballs and other. We also sell other items like art and music on eBay depending on it's value and if there is a market for it on the site.

Business Model: Flat Fee and Deadline-Driven Execution

A.C. Lion operates on a flat-fee model. The fee structure is fixed and disclosed upfront — it is not a percentage of sale proceeds and does not vary based on auction outcomes. This is the structural basis of the business: clients know their cost before the engagement begins, and A.C. Lion's incentive is to execute efficiently within the agreed timeline rather than to extend the process.

Deadline-driven execution is similarly structural. A.C. Lion builds its intake, photography, listing, and auction-close workflow around a defined end date. This is relevant for estates with property sale timelines, probate deadlines, or family coordination requirements. For full detail on how the process works and what the fee covers, see Pricing and Process.
