As we all know, the Mint's quality control program has curtailed the releasing into circulation of many error types that were found pre - 2000. However, like die clashes, cuds are not detectable by coin wrapping machinery (though I do expect some of the larger cuds to be sufficiently mal-shaped and thus rejected by coin wrapping machinery) and are still making there way into present day circulated coins. So, the need is there to have a continuous up-dated reference for cuds.
Fred Weinberg, Mike Diamond and myself discussed the various ways of having this reference and finally agreed that with today's portable devices that can access the net, a web site would be the best way to go. Not only is it free to the user, but it can also hold almost unlimited data.
Presently, we are working on Cuds-on-coins.com and hope to have the site ready for publication to the net by the winter F.U.N. coin and currency show where it will be introduced.
This is the basic structure of the site and more than likely will have some minor changes:

Can we use some HELP? You bet we can!
If you do have images of coins with cuds, retained cuds, major die breaks, split dies, etc. (both full obverse and reverse images are preferred) and are willing to let us use them on this new site, please contact me at:
