After all, you won't have much competition!
I mostly sell higher-end women's lingerie, and my sales aren't anything compared to what they were a decade ago. In my niche, I do believe I'm lost in the crowd of mega-sellers. To be fair, though, a decade ago I (and my husband, who was alive then and was my partner in the business) had many more (like 8 times as many!) items up.
I don't think that the mega-sellers are the only reason why sales are down, though. I think that there are two other important reasons:
1) As eBay management has been tightening the screws on sellers — with higher and new fees, removing support for TurboLister, bringing in and giving special privileges to mega-sellers, etc. — many sellers have flat-out left the platform. And since most sellers are also buyers, this has meant that a lot of buyers have left, too. So there's just fewer buyers. And:
2) eBay management has destroyed the mystique that eBay once had. A couple of decades ago eBay was thought of as a wondrous, fun place where you could find just the thing you wanted, be it a one-of-a-kind tchotchke or a high-end bra at half the retail price, from another person just like you (the buyer). Now, thanks to bad management decisions, the eBay brand is destroyed. Management didn't understand what eBay was and tried to turn it into another Amazon. And I guess it sort of is now. But it generally has a much worse reputation than Amazon, so for non-unique items, sales are lagging.
You're lucky that your items are unique and scarce. You should be fine on eBay; and if, for some reason, you find that sales aren't what you'd like, there are a couple of other sites you can go to. (Alas, with lingerie, there really is no place else for me to go; eBay isn't just the 800-pound gorilla, it's the only gorilla!)
Since it's been a while since you were listing on eBay, feel free to let me know if you any questions about new listing procedures, etc. I'd honestly be happy to help.
