The Saddle Ridge Hoard of gold coins, discovered in northern California in 2013, boosted the population of 1877-S 20s by thirty-four examples, one of which was tied for Finest Known at PCGS MS65.  Three others tied for Second Finest honors at PCGS MS64.

In 2009, Brian Koller, a cataloguer for Heritage Numismatic Auctions, reported an 1877-S $20 with a repunched final A in AMERICA (the underlying A leans to the right).  Because dies from this period were created using hubs, where all of the design details and letterings derive from a master galvano, an anomaly such as a widely repunched letter is inexplicable.  Theories include: 1) the doubling existed on the galvano; 2) dies created from the galvano had repunched A's that were corrected in the dies or resultant hubs (hence the reason thjey haven't been seen before): and 3) a corrected galvano was made and all the old dies were discarded except one or two.  Koller considers the first scenario to be the most likely.

The high mintage and "common date" status accorded the 1877-S would naturally lead most people to believe that this date is easily obtained in any grade desired. However, although the 1877-S cannot really be called a rare date, it is also far from common, especially in uncirculated condition. Most known specimens grade from VF to AU. In choice or gem mint state, the 1877-S is rare and almost never available. Overall, this date is much more rare than the 1876-S and is comparable to the 1875-S, 1883-S, 1884-S and 1902-S although it is more rare than any of those dates in mint state.
