Be careful buying cheap loupes, especially off ebay. At three for $5 including shipping, don't expect too much, but they may suffice depending on your needs. If you plan on spending a lot of time looking at coins, consider buying quality glass... your eyes will thank you for it.
Ok well I cant seem to get a loupe but this is the best I can do for now I just want to know if the are authentic because I am selling them. I collect pennies so
And if someone could give me a round about idea of their grade for me to post when I am selling it I would greatly appreciate it
