Welcome. There has been renewed interest in Internationals of late. Auction prices seem to have gone through the roof, comparatively speaking. Live auctions I attend always have a few to several, it seems, and they're no longer $50-75. Pretty much the same thing with
ebay.
Selling them to a dealer will be easy, and will probably garner your lowest overall return (in terms of dollars, at least). If you're willing to invest time, take a look at the various ways they're broken down for sale on
ebay. By volume, by country, by set. I suspect that the smaller you are willing to go in breaking them down, the higher the overall dollar total will reach.
