I think if you submerge those bars in a mixture of nitric and suphuric acid those spots'll come right off!
Cut to three weeks later. Hmmm... Man on the phone wasn't entirely correct, as it turns out... Listing on BB for 10 x 10oz now says July delivery, rather than June/July. Makes me wonder, if silver spot price started crashing big time, I would have no opportunity to offload those bars on the way down, and would be stuck with the POS at the time they finally arrived. Not whinging, but it has been about six weeks, and I don't think I'd be buying with such a shipping delay again. It's the chance you take, I guess - spot could have skyrocketed and I'd be better off.... :/
small bars can be exchange easily. clean the spots with baking soda,salt, hot water and aluminum foil. shiny like new, no scratch.
