Sure, but pieces of history are more valuable when they’re in good or working condition, which should be taken into consideration when deciding what to offer. Two decades ago I was a reseller, professionally. I’d go to open air markets, yard sales, estate auctions etc, buy things cheap and sell them for what they were worth. Mostly I stuck to easy stuff, new in box/sealed items, but every now and then I’d dabble in highly collectible items if the price was right. I went to one estate auction where they were selling off a collection of a well-known brand of antique pottery, piece by piece. I bid on every piece, but they were all going for $500-$800; less than what they were worth but too expensive to make any real profit. The last piece I won for $85, couldn’t believe it, was gonna make a killing. Immediately upon researching the piece I discovered it was fake. Like an actual well-made counterfeit. Of course realized why I got it for 10% of value. I couldn’t take a total loss on it, so I listed it on eBay in an auction starting at $10. Posted tons of photos from every angle showing clearly that it was fake to anyone who knew what they were looking for. Listed “as-is,” “no knowledge of manufacture date,” etc. It sold for $18, and I still had to give a refund to the winner of the auction because they eventually figured out it was fake for themselves. Just saying, any reseller has the ability to learn how to properly test/check the quality or authenticity of an item, so if they say that they’re unwilling/unable to, my first thought is that they’ve actually done it and just don’t want to tell you. I’d pay $300 for a piece labeled as “xxxxxx doesn’t work” over paying $400 for a piece labeled as “untested” any day.
