There’s no promise the figurine your grandmother left you or grandpa’s collection of signed baseballs will be worth thousands. We’re betting the owner of this Lalique Alicante vase knew it was valuable before Mastro Auctions in Burr Ridge sold it for almost $50,000. But if you’re curious about the value of something you inherited, purchased or found, the auction house will give you a free evaluation. The second Monday of each month is “Consignment Monday” at the auction house, 7900 S. Madison St., Burr Ridge. On April 14 and every second Monday, you can bring in two items from 1 to 4 p.m. Appraisers will look them over and give you an idea of their value. Click Here for full story.
