[QUOTE="HawkeEye, post: 3586252, member: 86305"]Of all the coins we collect, grading the Stone Mountain Half has proven to be the most difficult. A coin with features designed to intentionally be somewhat soft and with no flat field can be difficult. The stars can be an indicator of the completeness of the strike for MS coins, and an indicator of wear for circulated coins. But locating all 35 stars has been a challenge for most coins because rarely is the strike complete. To solve this dilemma we have developed a template we can electronically overlay on the large coin images to find traces of the stars. This is a Mint State example with the stars easily located. [ATTACH=full]957659[/ATTACH] But down at grade VG08 and below this becomes quite a challenge! [ATTACH=full]957660[/ATTACH] So our little overlay trick has really helped. The stars are often more visible with high quality images than with the coin under magnification because the actual location of the stars can be quite a challenge once they begin to fade. A good tool that may apply to other coins if they have soft features.[/QUOTE]
