have tried to sell surplus doll patterns on eBay. Some sell (by
designers) and some do not. When sold it is often at below market
prices, unless rare.
have learned that there are sites and clubs for vintage pattern
For an on line catalogue try http://www.olddollpatterns.com/
you were to sell a doll on eBay you probably would not get full
market value but you can put a 'reserve' on it so that if the
price you want is not met then there is no sale. There is or soon
will be an extra charge for "reserve" items.
the market by observing before you jump in with a buy or a sell.
you see an item you sort of like click on "Watch this item"
on the right column and it will be placed in your 'My eBay' Watch
how the money moves. That's an education in itself.
