This notice is only for subscribers to Premium Extended Features (less than 100). We just completed the image and data matching for the upcoming Rumsey sales and Siegel sales. The Rumsey Westpex and Hawaii sales have 250 matches with previous offerings at StampAuctionNetwork and you can use this information to help in bidding. The provenance and Census information is available from the catalog listings or you can access it by using the Extended Features dropdown and pull up the Provenance and Census Screening tool. While Siegel is no longer running their auctions at StampAuctionNetwork, the system is able to screen their catalogs as well and provide similar analysis (over 200 lots have been offered at StampAuctionNetwork previously). I am glad to help with any questions.
