[QUOTE="GDJMSP, post: 302281, member: 112"]I can understand the need to help vision problems clembo - no way around that. And higher x is often needed to identify some varieties or possible authentication issues. But when examining coins with magnification, more is not better for most people. It is in fact far worse in most cases. But most people don't realize this. That's why I always mention it when the subject comes up. What is desirable in a magnifying glass or loupe, for use with coins - is a quality lens, as large a field of vision as you can get ( in other words a large lens ), and a lens of medium power, generally 5x. Any more magnification than that tends to make you focus on things that you should not be focusing on. And this will eventually cause you to consistently under-grade your coins.[/QUOTE]
