I find most eBay bids come in during the last few minutes or even seconds.
But with items like yours I would be VERY wary of selling on eBay.
A 'proper' auction house would be a lot better. Auction houses have huge data bases of people who buy particular types of item. When they get a 'specialist' item for sale they are searching their data for potential buyers. They send these buyers advance notice and details of the item due for sale
As said eBay does not have the reputation for selling valuable collectors items that the big auction houses have. So 'serious'collectors tend to avoid it.
By the way I very frequently put an eBay item 'on watch' with no intention of bidding on it, I am just curious as to how much it will sell for, or doing research to see what a similar item to one I want to sell has sold for.
Finally a lot (even a majority) of eBay users will not buy from a seller with a low feedback or a new seller ( who will have zero feedback) Yes, I know it's stupid but it happens all the time. Get some feed back by buying a few cheap items on eBay, once you have a feedback of even 5 or 10 people will be much more interested in buying from you.
My eBay feedback is 599 and 100% positive, it has taken 3 or 4 years to build it up to that level.
