Your collection of Hull art pottery, 73 pieces, would have an average value of $40 to $200 each depending on the piece,
so the whole collection would bring about $10,000 to $14,000 in the current secondary market for this pottery.
The cabinet dates to 1905 to 1915 and has a current value of $300.00. These are sale prices which differ greatly from
any appraised value that you might have gotten years ago for insurance purposes. For example, if you were to add this same collection
to your home insurance policy today, you would insure the pottery for $40,000 insurance/replacement value (a general rule of 3x retail value for insurance)
Some sites that I recommend for selling are Varagesale.com, Ioffer.com, Ebay and letgo.com.
You can also go to invaluable.com or liveauctioneers.com and search their directory for an auction house near you and consign to them, which might be the best alternative in this case since you do have such a large collection.
