Sentry Hard Assets LLC review: The prices of this company are too high

I received the offer from Sentry Hard Assets LLC about the silver Franklin Half Dollars in original mint rolls. The price was $300 per roll, but after I agreed they started to increase the price. But all problems started, when I tried to sell these rolls. I found out that I have overpaid for them and no one wanted to purchase these rolls for such high price. Don’t do business with this company and be aware of their high prices.
