I have a decent size coin collection ( US and World ). There is a nice, free feature on http://coins.heritagegalleries.com/ which automatically keeps track of price trends for your collection of US coins. It doesn't have price data on foreign coins. Does anyone know of a free or very cheap service for foreign coins? Alternatively, does anyone have a favorite piece of coin-collecting software? I'm not very active in the market, but I like checking the total value so I know whether to revisit my insurance policy ( my mother actually had a very valuable collection stolen many years ago and was only reimbursed for face value ).
