I was wondering if anyone knew if this S.R. Mitchell 1 kilo silver bar might be a collectable type and a bit more valuable than the average bar? I see on the Engelhard site this type of bar is listed with an estimated mintage of less than 2,000. https://allengelhard.com/s-r-mitchell-co-pty-ltd/
Reminds me of a stacker who said he was looking out the window one day and noticed a lead curtain weight, and suddenly remembered where he had lost some 1oz gold coins.
