Business ProfileforMecum Auctions

I purchased 2 advertising signs from Mecum. 09/26/2022 purchased a Globe Ethyl Double sided porcelain, advertised as an original. I paid $3950 for. On 01/19/2023, I purchased a ****** sales and Service single sided porcelain sign from Mecum, advertised as Original for $$3096. I recently took these items to ******* Auctions to resell. I was told by ******** auctions (they also have a sign authentication company), that these items are not authentic, non originals. So this means the signs I purchased for over $7000 and was sold to me as originals, are in fact fantasy pieces with a worth of maybe around $200. My first purchase was in person at an event. I spoke with a Mecum rep working that auction and he assured me the Globe sign was original as stated in their advertisment.. I asked because I didn't want to buy a fake and I told him that. Second sign was an online purchase, that Mecum advertised as "Guaranteed Original". Neither sign was what they claimed. Nor would I have purchased these items knowing they were fake. Mecum auctions sells other signs which they don't list as originals, but these two signs they did advertise as originals. By advertising these signs as originals they falsely caused me and others to overbid and pay an inflated price for a product worth a fraction of what was paid. Again, this is how they deceptively sold me these signs. Since they are in the business of selling these types of products, one might reasonably assume they know the difference between real and fake. The fact is they labeled these signs as original. They sell other signs where they do not list as originals. I'm looking to return these signs back to Mecum and get a full refund of my purchase price.
