OK Unitrade 2016 has me completely stumped! Unitrade lists 3-4 different printings for each of the berries values, depending on printer How in the world do you tell them apart - Unitrade gives no information First Printing is Ashton-Potter on CP paper Second Printing is CBN on Harrison paper Third printing is CBN on CP paper Final Printing is Ashton-Potter Ltd on CP paper Harrison Paper and CP paper both have a greenish tinge to the gum - Harrison maybe a bit darker but for the other three prints - all on the same paper, so how in the world are they differentiated? Do you need margin corner blocks to verify print? Any adivce more than welcome here0 Gene |

Yes - the inscription would be needed to tell what's what unfortunately! It would have been nice if they could have added something to the design to differentiate theirs from others!

I understand your frustration Gene! I was the same, so I simply decided to skip trying to differentiate them all toghether. The study of the Small Queens and the Centennials had largely exhausted my patience with Canadian stamps at that point anyway, so I allowed myself the 'short-cut'  This post wasn't helpful at all, I know, just saying you don't HAVE to solve the mystery!  |

OK Unitrade 2016 has me completely stumped! Unitrade lists 3-4 different printings for each of the berries values, depending on printer How in the world do you tell them apart - Unitrade gives no information There is information in the front of the catalogue (at least there is as of 2018 - I have only that edition and the 2020 edition easily at hand at the moment). You'll notice in your listing that many of the used prices are missing values, showing just a dash instead. That's because it's too difficult to tell which printing is which once the gum has been removed. Notice this line from the catalogue - "Most of these manufacturers produce paper literally indistinguishable from the others and for that reason the name of the stamp paper manufacturer is of no more consequence than the name of the tree from which its paper was made." The first chart shows a list of stamps which are available with only one single type of paper, so it allows you to build a reference collection of sorts. The second chart tries to give a description of the paper types, but again, some of them are so close to the same that you can't count on being able to tell one from the other.    Ryan |

So looks like the answer is to collect the berries with attached inscription label denoting the printer. Looks like I'll be needing 4 sets of inscription blocks then to be able to have the sets (thankfully these are low value definitives so not too expensive, just have to hunt to get the whole sets).

There is actually a way to tell them apart, but it requires a great deal of patience and some experience working with the inscription copies to get a feel for the printing differences. I haven't written about them in a long time and I will be writing and publishing a detailed blog post about this issue in the new year. But what I can tell you now is:
1. The original Ashton Potter printings all show a very light vertical ribbing on the printed surface that can best be seen by holding the stamps at an angle to a good, strong light source. They are on CPP paper, so the gum will be flat and somewhat greenish.
2. The CBN printings on Harrison paper are a cinch because the gum on Harrison paper has a sheen to it, has irregular blemishes and it makes the stamps curl.
That leaves you with Ashton Potter Canada and the CBN printings on CPP - much tougher. My recollection is that the difference lies in the shades with the green and yellow green being brighter on the APC printings and the blue of the sky being slightly brighter. But I will confirm that when I lot my Berries and Flag stamps for the auction I will be holding in the new year and when I write and publish the blog post, which I will share the link to here after I publish it.
