The 4-ring dumb barred canceller was used throughout the run, but the cancellations with the words "CANCELLED" or "INUTIL" in an oval cancel were only used between 1861 and 1867. It doesn't speak to the underlying stamp of course, but if so cancelled, is more likely to be a stamp issued in that period.

But what one countries experts call "sky blue", may be a different "sky blue" for another countries experts. Those that expertise usually have an already certified example of a stamp that they refer to when evaluating a candidate. I know, very primitive, but that is what we have. ;-)Jimhttps://www.blogger.com/profile/02024632082262694589noreply@blogger.comtag:blogger.com,1999:blog-6190925726844102948.post-68120667652113193742020-05-17T08:27:03.908-07:002020-05-17T08:27:03.908-07:00Interesting, Jim - thanks.

Hard enough making some calls to determine which stamps get placed into my BB; I wonder how expertizers do it, especially when a shade here or there can mean the difference in $$$ in CV. <br /><br />Makes me wonder if there's a more scientific way that could be developed, but I'll leave that question for the more laboratory-oriented minds out there!Tom Lnoreply@blogger.comtag:blogger.com,1999:blog-6190925726844102948.post-3838249083016689432020-05-15T06:53:11.712-07:002020-05-15T06:53:11.712-07:00Thanks Tom. :-)

There is a U.S. color chart- but that only applies to U.S. stamps, for instance. I notice the Stanley Gibbons catalog sometimes has a different color description for the stamp- that offers a clue. Looking at other people's collections on-line or stamp websites for the country are helpful. Lots of experience is helpful. ;-)Jimhttps://www.blogger.com/profile/02024632082262694589noreply@blogger.comtag:blogger.com,1999:blog-6190925726844102948.post-8072987416369835232020-05-15T06:35:41.716-07:002020-05-15T06:35:41.716-07:00Woof - definitely a steeper learning curve here.

Thanks for putting together! <br /><br />By the way, not sure what happened to your recent Colombia post, but it got me wondering - is there a definitive (or just super helpful) resource available to accurately determine stamp colors? Have had a hard time telling shades of red apart (for example). Thanks!Tom Lnoreply@blogger.com
