Would you buy Gold/Silver ingots or coins from me?

I wanted to ask you guys outright as I noticed there's obviously quite a market for ingots and coins out there when it comes to working with Gold/Silver, I've been seriously considering expanding on my skills and not only looking at Jewellery but the actual refining and casting of precious metals myself so I can maybe get into making money from people who want to purchase Gold/Silver as investment rather than for the Jewellery side of it. Would you buy ingots or coins from me if I made sure they were pure and showed you proof? I've been looking into stuff like using nitric acid to refine silver but it might be awhile before I can actually go ahead and do this as I need to get everything set up, plus I've got other projects going on at the moment obviously too.

These would all be made from scratch and be unique to my brand so there wouldn't be any re-selling going on.
