Hello! This is the first time I post to the forum. I'm a numismatist working with ancient Greek coins. I'm trying to examine the normal distribution of the databases I created: c. 25,000 coins. For this reasons, I QQ plotted coins from my main database (c. 8,200 coins) versus those from collections. You have the results in the attached file. I'm not a specialist of the method and I would like to ask you what you understand from the graphs? In my reading, the different samples are equally distributed, since all three (in one case) and four (in the second case) are close to the same line. Any help would be more than welcome!

Thank you in advance!
