Visited my mom this weekend and came upon old Royal Dutch Petroleum Company preferred shares. I had forgotton I had recieved them as a gift when I was 13. Now I know Royal Dutch was sold in 2005 to Shell oil. How would I go about finding if there is any value to these shares, and how I can cash in on them? I have included an image of the front of the share. I also have dividends pages, but did not scan those.
Any info would be greatly appreciated
