Your hemming tool is not actually a hemming bird. Those actually have the shape of a bird as part of the design.
Your pieces date early 20thC.
The hemming clamp has an estimated retail value of $95-120.
The lovely inlaid wood tape spools would have an estimated retail value of $75-90 each.
Online auctions like eBay generally bring wholesale selling prices.
If you would like to sell close to estimated retail, some ideas are:
The internet has your largest audience of buyers. Place small ads on these sites or set up your own small store on these sites.
Etsy.com - small fees - 20 cents to list plus 3.5% final price.
Amazon Marketplace: http://services.amazon.com/content/sell-on-amazon.htm/ref=footer_soa?ld=AZFSSOA
Or your nearest CraigsList.com where you can list items for free.
These sites are excellent and more upscale but fees are higher. I only recommend them if you have several items to sell.
In general, a private seller to a dealer or at auction can expect 30-60% of estimated retail value.
