NO Moller Rosewood Dining Table and four JL Moller Rosewood Dining Chairs

I've had this set for years, was a hand me down from the ex in-laws. It's Rosewood, circa late 50's or early to mid 60's. Purchased new, used regularly, even to date.

I am trying to find out what it is worth. I've seen the same set priced anywhere from $250-$1800 per chair and the table anywhere from $500 - $10,000.

The table is marked NO Moller and the chairs are marked JL Moller.
