Like any good investor, I am not advocating putting all your eggs in one basket (especially ball cards). However, if this individual has decided they want to buy some cards towards this end, there are some cards out there they could purchase today, and perhaps if chosen wisely, could increase in value over time. I don't think the lady you mention is relevant here as late 70s whatever she was interested has no history of past sales, etc. So, the relevant question still remains, what cards are currently undervalued?
