its pretty easy to tell whether something is solid gold or gold plated when you dig it.
Every item I have dug an item that is solid gold it didnt need any cleaning other than a rinse with soap and water. If there is any corrosion or peeling on the gold part then its just plated base metal.
You can rub my face with that watch anytime. In fact I could try to open it for you. I work in constructions and I'm sure I can find the proper tool for this. Just sent it to me. Please! Thank you! Welcome! Don't mention it!
I'll send it to Warren first... it'll cost less!![]
Besides, I got a BFH too (Big Friggin Hammer) so if I want to try to open it myself, I'll use the tools my father told me could fix anything... a screwdriver, a pair of vice grips and a ball peen hammer (aka BFH)[]
