My name is Mike Jacobson, owner of Cook County Buyers Inc.
I started this business over seven years ago buying diamonds and gold jewelry and have been in the business my whole life. I decided that I could do a better job than the corporate gold buyer stores, or local pawn shops and have grown into a top choice in Chicago land for individuals looking to sell their items. Everyone claims to pay the most when its time to sell gold, but I can deliver because I have zero employees, a tiny office, and minimal expenses.
For Gold I work on an average profit margin of 20% to 25% - This translates into a higher payout to you, the seller, meaning if I pay you $1000 for your gold, when I sell it to the refiner, it will net me around $1200 to $1250 depending on what happens to the price of gold.
Another advantage to selling gold and diamonds to Cook County Buyer, Inc. - You get to work one on one directly with me, and I will explain what your item is worth and guide you through the process without any rush or pressure. Rarely is a seller given an opportunity to sit with a knowledgeable buyer and have all of her questions answered and her items evaluated right in front of her, ending with cash in hand payment.
