That would depend on the materials, and how extensive the restoration.

I have looked at a lot of modern cards under both short and longwave (why not, I had the light ) And the inks react differently.
I don't have much for fakes or altered cards to compare to real ones.

The typical dual wave units are not sub $10 cheap, but they're not horribly expensive either, usually around $35.

The one I have that's not working was a lot more powerful, but runs $100+ and is getting hard to find. It really lit stuff up compared to the smaller unit I have now.
For shortwave you should probably at least wear glasses with polycarbonate lenses to block the UV. Some people get headaches etc after some exposure.
