The amount of aged wines on the market is astronomical, and yes there are instances of fraud, as I watch in magazines such as Wine Enthusiast and Vineyard Magazines. Do you follow wines? When a fraud is discovered, it does make the wine news, as there are many wine market related magazines. And, when discovered, who discovers them? Sommeliers. But, it isn't exactly riddled with frauds.
The pipe tobacco market isn't as vast, merely a drop of water next to the bucket of wine trades. But, we do see some folks not holding up their ends of trades here. And, how does someone buying a jar of something know if the dates on the label are correct, or even if it really is what it says it is. No one is exactly policing the trades as with wines.
The reason I made the comparison was to show that comparing wines to tobacco isn't necessarily the same. Wine is regulated somewhat, and sure maybe some fraud slips through undetected, but at least there is an attempt at regulating it. I wouldn't dare try to sell a bottle for thousands without having someone authenticate it and handle the transactions for me.
And, as a winemaker, I would not even sell one single bottle without having all of my t's crossed and i's dotted, even if it isn't worth even $100. There are laws in place, and while I may not agree with all of them, I am not going to risk anything without being ready to pay the penalties. Thus, I would only buy from a pipe tobacco secondary market such as Pipestud, which is as close to being regulated as we have in pipe tobaccos. But, even then... I am not going to buy a jar of something. But, to each their own. Just posting my opinion, like everyone else.
