Having a fair trade system is important in order to make successful trades over time. If you’re looking for great coins please don’t try to take advantage of other traders that might be less experienced in collecting. If you bring junk expect to only trade junk.  We won’t tolerate people being taken advantage of, we run a good site that will enforce fair standards. Once you have cross the line you will receive a warning and if you think you’re slick and try it again you will receive a ban. The younger collector’s should always seek advice when in doubt at the challenge coin forum .
