The 1893 Morgan Silver Dollar is no chump change. In fact, the coin can be worth up to $90,000 if it’s in mint condition; but the one THR and Associates, the International Coin Collectors Association, bought Wednesday, Jan. 4 from a Longboater for $6,000, is expected to be worth $10,000. One couple brought in a coffee tin full of silver coins to the Longboat Key Hilton Beachfront Resort and walked out with $8,000. After the company purchases these coins, the coins go to a processing company through which they are graded. The company collected jewelry, knick-knacks and silverware.
