Sesqui $2.50 Gold Commem MS66
In this new feature, we explore a specific issue that saw a price change this week, with an analysis of what motivated our decision.


This issue's "Featured Coin" gave us fits because the Sesqui $2.50 in MS66 has sold for a dizzying array of prices in the past years, ranging from $3,300 to $9,300. Auction results in MS66 have been all over the place, so we spent some time puzzling over how to best determine "Bids" by studying auction records, observing exchange bids*, and soliciting feedback from known traders in this issue.

At the moment, the sight seen "Bid" for this coin on CoinPlex is $7,500. However, the last five auction results in 2015 tell a different story:

  • August 2015, MS66 NGC: realized $3,995
  • July 2015, MS66 PCGS: realized $5,288
  • June 2015, MS66 NGC realized: $4,700
  • April 2015, MS66 PCGS realized: $3,290
  • January 2015, MS66 PCGS: realized $6,463

Given that the Bluesheet is a "sight unseen" publication, the question was where to set the price given these varying prices realized. The Sesqui in MS66 is not exactly common either -- there are 273 total examples graded at the two major grading services. Additionally, none of the sales above were for coins with a CAC sticker, which would warrant a value of $7,500, or more.

In the end, some subjective decisions were required to arrive at an accurate price. We determined a baseline Bluesheet value of $3,800 for both PCGS and NGC certified coins. The lowest price of $3,290 appears to be as an anomaly as this price represents what we feel an average-for-the-grade coin is apt to trade at.
