Updating, with a lag, my data for U.S. Mint sales of gold coins, here is 1Q 2017 in its full glory.
Total sales of U.S. Mint gold coins stood at 221,500 oz in 1Q 2017, down from 363,000 oz in 4Q 2016 and down on 305,500 oz in 1Q 2016. However, 1Q 2017 sales were better than 1Q sales in both 2014 and 2015.
Total number of coins sold by the U.S. Mint stood at 438,000 in 1Q 2017, down on 647,500 in 1Q 2016. In terms of number of coins sold, 1Q 2017 was the slowest of all 1Q periods since 1Q 2012.
Average weight per coin sold was 0.5057 oz/coin, stronger than in 1Q 2016 (0.4718 oz/coin) and stronger than 1Q average coin weight for 2014 and 2015.
Monthly data, plotted alongside historical and period averages shows that more recent months (especially April) posted weak sales performance.
Meanwhile, a look at quarterly aggregates indicates that while 1Q was weaker than 4Q 2016, it is still in line with the generally upward trend that has been present (with some serious volatility) since the end of 2013.
Both, the monthly series and the quarterly aggregates indicate relatively stable and strong negative correlations between the price of gold and the demand for U.S. Mint coinage over the last 6 months within the range of -0.62 and -0.84.
