We have received numerous messages this week – not unexpectedly – regarding the location of the prices of what were previously called “Proof Singles” that were in the Monthly Supplement. These were not omitted by accident but rather due to space limitations for the initial Monthly Greysheet. We are currently redesigning the layout to include these prices for the next Monthly Greysheet, which will be found with their respective coin series rather than all together in one chart. For instance, proof Washington quarters will follow the mint state Washington quarters prices. We would also like to advise that these prices are still available on our online price guide (www.coinprices.com) and via the CDN Pricing app.
