Yes, which series or sub series is it? we all often notice some reservation, or suggestions that it is hard to grade from images. comments are: Oh get us better pictures or similar. and often a member says: that is without daubt a MS.. or G... and makes a solid statement of a grade. I have often experienced after having bought a coin on seeing images only, that I was very disappointed when I finally had the coin in hand. Very few times the surprise was pleasant, What is your opinion on this subject? CANADIAN and Can provincial coins only please?
For me, almost any coin that is supposedly UNC, I really can't tell from images, because the photography and lighting can make 2-3 point differences and maybe more if scratches or cleaning took place. I think that Newfie coins and Geo 5 cents also tough.
In Canadian series . George V Five Cent Nickels first , closely followed by George VI Five Cent Nickels . Both have strike issues . A third series that causes issues Edward VII silver coins dated 1902 1907 , the 1908 - 1910 Ottawa issues are generally much better strikes than the earlier London and Heaton coins . The grading companies are all over the road map on the above series . You could submit the same coin 4 times and get 8 different opinions ( sarc intended ) .
