Hi Goldstein, thank you so much for the book! that is a good lead. I agree in the point that you make about history. That was my major actually. And I am enjoying way more learning about historical facts, kings, economy, events and cultural processes through silver than in boring exams. I find it amazing that the silver can tell us so many human stories with its style, the hallmarks, the scarcity (in this case), and many other variables. I hope to keep learning about it more and more every day, and every piece that I buy. Then, I have to disagree a little bit, to buy something I don't know and asking others (usually google) it has been always a really fulfilling and financial gains. I rarely buy over the price of scrap silver. But I think I get the point of what you meant, in the sense of collecting without information it leads to failure.

To add something about your info about the Russian revolution and its effects in silver: it started in 1905, and one of the many things that the people did to protest against the Tsar was to withdraw all their savings (silver coins) from the state bank, forcing the Empire to melt its own silver to pay its debts.
