“Keep in mind that all of those options involve selling costs, time, labor, etc.”
Yes, that’s the thing. That’s why I’m thinking of seeing what the antique place will give me (though I know it will probably be less than what I could get, but little of my time, labor, and various costs involved).
I’ve done research and made an Excel spreadsheet of what I have (I’ve found jewelry boxes for most and it’s a heavy box ful). If she goes too low, I may do a garage sale with just jewelry and potentially Hallmark ornaments (I have a lot of those to sell) and advertise the sale on craigslist.
Sounds like you’ve done your homework. If you do end up advertising a garage sale, make sure you specify it’s costume jewelry, or you might end up with some un-welcome, un-scheduled visitors.
Would love to see a pic if you have one.
