Since the 1999 Dow/Gold ratio peak, silver was only able to reach around $49, just short of the 1980 high of $50 (not so clear on the chart since it deals with monthly prices). This tells me that all-time highs are still coming. Interest rates are also a very important economic measure, especially for silver prices, as explained previously (explained for gold, but also applies to silver). A period after a major interest rate bottom is generally great for silver.
