I do not want to mislead you. I could not locate your exact series of marks after an extensive search. I know from experience that there are many American and Canadian coin silversmiths that used a bird or a star or both in their marks. There are also many unlisted American and Canadian coin silversmiths and retailers during the 18th and 19thC up until about 1870s. Very, very little is written about the Canadian silversmiths of this period.
There was a prominent silversmith based in Montreal from 1837-1895. named Robert Hendry. I believe he is most likely the one on your spoons. In all my searching, I did not locate a Brokaw silversmith or retailer of silver.
It is reasonable to assume your coin silver spoons were made by a Canadian firm ca 1850-1870s.
The set of spoons would have an estimated retail value of $225-250 assuming good condition and depending on sale geographic location.
These spoons would be worth more, perhaps $300, if the maker was famous.
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.
These sites carry antique as well as vintage items.
Accept PayPal only.
Etsy.com - small fees - 20 cents to list plus 3.5% final price.
Or your nearest CraigsList.com where you can list items for free. Accept cash only.
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, via consignment or at auction can expect 30-50% of estimated retail value.
Insurance replacement values are usually about 10% more than retail values.
