Hi,
You can use the advanced search function on eBay to search for "sold listings". I suggest starting with the term "millefiori trade beads". I tried it just now and got over 680 sold items that you can scan through to get an idea of what your beads are worth.

If you have any flat, tabular-shaped millefiori beads, or rounds, they will be worth more than the common cylindrical variety.

Anything you'd like comments on - please post! And note that you have to reduce your pix to 256k or less. You may have to use a reduction program to do this. If you use a Mac, this is easy to do by loading into iPhoto, then exporting the pic as Medium size and Medium quality. I don't know the best way to do this with Windows.
