Authenticated Sports Memorabilia
Signed jerseys, helmets, balls, framed displays, and one-of-a-kind collectibles, selected around the teams and athletes your guests actually care about.
Charity Auction Fundraising Company
Diamonds in the Rough is a charity auction fundraising company that provides authenticated sports and music memorabilia, plus the bidding tools to sell it, to nonprofits running fundraising events. Your beneficiary receives guaranteed funds from the first bid, and 100 percent of everything above that goes straight to your cause. Since 2011 we have helped organizations raise more than $17 million, and we now support over 600 events a year across Texas, Oklahoma, Louisiana, and Colorado.
How It Works, and Why There Is No Risk to Your Organization
Most fundraising auctions ask the organization to source items, front costs, or chase donations. We do it differently. We bring the inventory, hand-selected and fully authenticated, and your beneficiary is guaranteed proceeds starting with the very first bid. Anything the items sell for beyond that guarantee goes entirely to your cause. Your committee does not buy inventory, carry unsold items, or take on financial exposure to run a strong auction.
Every Item Is Fully Authenticated
Authenticity is what separates memorabilia that drives real bidding from items your guests quietly ignore. Every collectible we provide is authenticated by the industry's trusted authorities, JSA, Beckett, and PSA/DNA, and carries our tamper-proof hologram. Your bidders know exactly what they are buying, which is what gives them the confidence to bid higher.
What We Provide
Music and Entertainment Memorabilia
Framed guitars, signed vinyl, and entertainment collectibles for events where the crowd runs broader than sports.
Auction and Bidding Solutions
Silent auctions, live auction lots, and mobile bidding software, set up and run so the process is smooth for your team and easy for your guests. If your event already has a live auctioneer, we supply the items that give them something worth calling.
Autograph Signings
In-person signing experiences that give your event a draw beyond the auction table.
Built for Galas and Golf Tournaments
We work every kind of charity fundraiser, but two formats are our specialty. Black-tie galas, where the right marquee item anchors the night and sets the tone for the room. And golf tournaments, where sports memorabilia lands with an audience that is already there for the game. Both reward inventory chosen with the local crowd in mind, which is exactly how we select.
Organizations We Work With
Nonprofits, foundations, associations, and charitable organizations across the region trust us with their fundraising events, including the Houston Food Bank, United Way of Greater Houston, the American Cancer Society, First Tee of Greater Dallas, the Dallas Fraternal Order of Police, Folds of Honor South Texas, the Southern Texas PGA, the Junior League of The Woodlands, and the Texas Sports Hall of Fame.
Where We Work
We serve charity events across Texas, Oklahoma, Louisiana, and Colorado, with dedicated focus on the four largest Texas metros:
Frequently Asked Questions
What does a charity auction fundraising company do?
We provide the auction items and the bidding solutions that make a fundraising event profitable. That means authenticated sports and music memorabilia, silent and live auction lots, and mobile bidding software, with guaranteed funds to your beneficiary from the first bid.
How does the guarantee work?
Your beneficiary receives guaranteed proceeds starting with the first bid on our items, and 100 percent of anything above that guarantee goes directly to your cause. Your organization does not purchase inventory or carry financial risk to run the auction.
Do you provide the auctioneer?
No. We provide the memorabilia and the bidding solutions. Most events with a live auction already have their auctioneer, and we partner with live auctioneers rather than replacing them. Our role is making sure they have items worth bidding on.
How do you authenticate your memorabilia?
Every item is authenticated by JSA, Beckett, or PSA/DNA, the industry's most trusted authenticators, and carries a tamper-proof hologram. Bidders can verify exactly what they are buying, which is what supports higher bidding.
What kinds of events do you work?
Galas, golf tournaments, benefit dinners, and charity fundraisers of every size. Galas and golf tournaments are our specialty. We support over 600 events a year.
What areas do you serve?
Texas, Oklahoma, Louisiana, and Colorado, with dedicated focus on Dallas, Austin, San Antonio, and Houston.
What if items do not sell?
Your beneficiary's guaranteed proceeds are not contingent on a particular result, the guarantee starts at the first bid. Your organization is not left holding unsold inventory or covering costs.
How far in advance should we book?
The earlier the better, especially during gala and tournament season. Booking ahead gives time to curate items around your specific audience, which is what drives bidding. Book your event.
