1936-S Bay Bridge Opening. MS-67+ (PCGS).A captivating piece, both sides sport smooth, billowy mint frost to overall brilliant surfaces. Only in isolated peripheral areas on the obverse do we see some subtle orange-russet highlights, which are notably more extensive around the entire reverse border. The Bay Bridge Opening is a scarce to rare commemorative half dollar at and above the MS-67 grade level that represents a significant find for the advanced collector when such coins are offered in todays market.
