[QUOTE="TIF, post: 3054761, member: 56859"]Good eye! Different lighting, color vs black and white, image resolution, and other factors can make matching old pictures to an in-hand coin very tricky! Some old images are of casts, introducing another variable. Even more extreme are the Dattari plate images vs. real life. The Dattari images are pencil rubbings so many details, including key things which are very helpful in matching a coin (the coin's outline, for instance), may not be visible or may be misleading. Some examples: [IMG]https://www.cointalk.com/attachments/tiberiusobolhippo-dattaricollection-rt-jpg.553274/[/IMG] [B]EGYPT, Alexandria.
