I have heard about black light for years, but I have never bothered to look into it. So here goes:
Is there anyone here who uses it? What are some of the things that you can see on cards that aren't visible under normal light? If you can provide examples or upload pictures, then that would be great. Do you think that it's important to own one, especially for collectors who like to spend big money?
I heard that companies like PSA use black light only on expensive cards - is this true? So does this mean that cheaper cards have a higher chance of passing through?
And finally, I see so many different ones on eBay - which one is good? A torch? A bar? Can someone on here explain the specs a little more to me? I see so many different numbers.
Thanks for your post
