Spectrum Group International has moved to a new Location to serve you better!

As of November 28, 2011, Spectrum Group International and our U.S. collectibles companies are relocating. The new building is still conveniently located in Irvine, California, not far from our previous location. It is larger and very modern and our expansion will allow us to provide our customers with even better opportunities for buying and selling their fine collectibles. We look forward to welcoming you to our new home!
