High End Memorabilia holds autograph auctions on LiveAuctioneers.com and iCollector.com. They were on Invaluable.com, but they can't hold auctions there anymore. The company started selling on these platforms in 2018.
High End Memorabilia is the same company as LuxeWest and Front Row Memorabilia, which sell autographs on Amazon, Wayfair, Touch of Modern, Houzz, Etsy, eBay, and other sites. You can also buy on their website, frontrowmemorabilia.com.
