It can be difficult with slabs, which lack pockets for dealer tickets.<br /><br />NGC Ancients does offer slabs with pedigree information. For example, this Athenian owl [ https://www.ngccoin.com/certlookup/4629456-016/NGCAncients/ ] records "ex Sotheby's (3/97), 94" right on the slab.<br /><br />NGC's web site <a href="https://www.ngccoin.com/specialty-services/ancient-coins/attributions.aspx" rel="nofollow">says</a> 'the submitter must provide supporting documentation (photocopies from auction catalogs, etc.)'. It would be nice if<br />the slab company allowed the submitter to submit any provenance, no matter how sloppy, to be scanned and stored<br />on the slab verification web site.<br /><br />Auction houses put stickers on the slabs, but only for their own auction. I am keeping my slabs in <a href="https://www.wizardcoinsupply.com/slab-protectors.html" rel="nofollow">slab protector sleeves</a><br />but instead of using the sleeves for protection I use them to hold paper with some notes.<br /><br />It is easy to imagine that my records will be available when it comes time to sell my collection. The truth is that if something<br />happens to me, or to my house, any records kept separate from the coins are likely to be lost forever.Ed Sniblehttps://www.blogger.com/profile/17346392312959087285noreply@blogger.comtag:blogger.com,1999:blog-19567381.post-76388483454841219302018-09-13T13:12:23.898-04:002018-09-13T13:12:23.898-04:00The problem with these population reports at least...The problem with these population reports at least for modern coins is that coins are frequently broken out of slabs and re-submitted. Lots of double, even triple or quadruple counting the same coin. <br /><br />Of course, if the slabs also tracked provenance, this would not be a problem. My biggest criticism is that all too often critical information is simply thrown out when a coin is slabbed. This is a real issue for ancients where provenance has become lots more important.
