david bullion stacking is not to collect the coins some serious investor like to have a set of date runs, so sometimes particular dates might all of sudden increase in value e.g 1988 silver 2 dollar, but then again mars 2 dollar coin its even more insane price increase.
some of the earlier lunar series in silver increase in value multiples x5-x4 in short time due in part also to the Iraq and Afghan war
ill say the worst collecting investment in part due to inflation as well and very low demand are the 5 dollar coins exchanged at the CBA (draws full of this stuff) I think at the time people can't even use them in regular circulation, and anyone buying them for above face :S good luck to you.
