FWIW... this is exactly why we launched Lollipuff (YC W13): https://www.lollipuff.com/

eBay is notoriously plagued with fakes. For some designer brands, fakes can account for 75% (or more) of the items sold [1,2].

The key for Lollipuff: We have brand experts authenticate each and every item -- ie. real, human experts augmented with sophisticated software to make things scalable. We like to think of it as "eBay without the fakes", or if you prefer "Palantir for designer goods" (software-augmented humans).

I notice you don't offer support for watches. Are there any plans to expand to that? I operate a similar website (http://www.haberdashboard.com) where I just implemented a watch search, and it is ASTONISHING how difficult paring out the fakes is.

I'm impressed by how much engagement you've built over such a small number of items. Is there a reason you don't seem to have implemented typical search filters like size, price etc? It seems difficult to find anything if I'm just browsing, so I assume I'm missing something as to how people are using the site.

The problem with watches is typically the only way to tell if it is real or not is to take it apart.

Are there not slight differences in weights from the real to the fakes? The eBay service mentions like-new items so I'm kind of assuming specs would be available.

It is common for fakes and real items to weigh the same: https://www.lollipuff.com/blog/133/pet-peeve-authentication-...

Even this isn't especially helpful with watches. For example, take this one: http://www.ebay.com/itm/WW2-BULOVA-MILITARY-WATCH-A-11-with-...

This seems to be a good example of a vintage A-11 military watch (it's listed as such). It looks correct. It's got pictures of the movement, which seems to be correct. The seller has almost perfect feedback. So no problem right?

It is 100% fake (or at least, a frankenwatch made from old and new parts). And this is for a watch worth, perhaps, $200.

The real problem with watches is that fakes are so difficult to recognize that buyer feedback means much less, since a buyer is unlikely to recognize the fake. And often a seller is unaware he's selling a fake, so deception can't be detected in the description or the title. For the watch above, I think the seller knows what he has, and has very carefully described it to imply that it is an original, while not technically lying (he only claims the CASE is original).

It's a very, very difficult problem to solve.

True story:

A friend of mine bought a cheap "Rolex" in Thailand.

It was only after he brought it home, he recognized that the calendar has 40 days, instead of 31.

Could the watch manufacturer print a UUID on each of its parts that you consider irreplaceable if it had to be fixed? The watch could then be verified using the serial number and some online database?

Conceptually, how do you guys triage the fakes? The spectrum of quality seems so broad, in that they are convincing enough to be worn on the red carpet (and presumably picked by stylists) etc. Or are all those shots authentic pieces that were then used in fake listings?

It takes some legwork up-front, but after that even the best fakes are pretty easy to spot if you have the right training and tools.

I can spot fakes for sneakers, but I assume it's the same process. Material, spotting the stitchings, logos, etc. Certain things line up, there's a certain distance between stitches and logos, etc. With purses, some are easy to spot by looking at the pattern, loose threading, discoloration, etc. Once you have an eye for it, it's pretty easy to spot cause it stands out like a sore thumb.

Is there still a market for fake-but-good items? If you had a designer purse that was 99.99% indistinguishable from a real one, could you still sell it to people at a big discount, informing them that it's a fake? I wonder if there are people who would gladly knowingly buy a good-quality counterfeit one. You'd still get the social benefit of designer goods, since no one else will know.

That is trademark infringement. You would be at risk of your products being seized and destroyed when they enter the US.

I'm sure there is a small market for this.

But, I think that most people do not want to buy a counterfeit on eBay. Ioffer provides much lower prices on fakes, oftentimes direct from China. For instance, on eBay, the average fake Chanel le boy still sells for over $1500, and a Celine mini luggage will sell for around $1400. There is no way that people are paying this kind of money knowingly for a counterfeit.

There are very few counterfeits that are 99.9% accurate. Most of the time I can spot a fake dress or bag on someone from <5 feet away. But, then again, I'm very familiar in this space.

Any proof to support the claim " I'm sure there is a small market for this."? I think there is a huge market for fake stuff in the US. Some people buy it intentionally, some dont. If you are paying $100 for an LV bag, its probably a fake or heavily used.

"Most of the time I can spot a fake dress or bag on someone from <5 feet away."

I'd be worried about survivorship bias. Perhaps you only "see" a sub-set of fakes (the un-convincing ones) and the good ones walk right on by. Isn't this problematic?
