Hello all, I have been looking to get a coin loupe! I have a gift card for amazon so I was hoping on getting one there. I have no clue what magnification I will need so i was hoping for some help like 20X, 30X, 40X? I would like to be able to make out fine details on my coins and maybe even tell errors. Also did anyone buy one on amazon that could you recommend a brand. Thanks to everyone in advance!
