The United States Mint has released an update to the Numismatic Pricing Grid for 2020. This is the pricing matrix that is used for the pricing ranges of Numismatic Gold, Commemorative Gold, Platinum, and Palladium products offered by the Mint.
For 2020, the revision of the Numismatic Pricing Grid already reflects the price increases coming to Platinum Proof coins.
Every Wednesday, the United States Mint evaluates the pricing of precious metal products. Pricing can vary weekly based upon the London Bullion Market Association’s average weekly prices. If the prices are above the ranges outlined in this grid, prices for these products will increase. Because of the price ranges used on the updated grid, mid-year price increases are rare but not unheard of. Generally speaking, bullion prices remain generally stable.
You can find the 2020 grid following this link. It is a PDF so you can open it up in your browser and save it to your PC for future reference if you so choose. Reading the grid is reasonably easy. The average price is in the left column while the columns to the right indicate the price of a particular Numismatic product when the bullion prices is in that average window.
