I have hundreds of very old valentine day cards, as well as Christmas greeting cards, most are from 1930s to 1960s. I have books filled front and back. Bought a unit at auction and came across them. They range from $10 up to $150 a card  and more depending on size and condition and mechanical wise and there are a lot of them...selling everything together. $350 also have a box of very old bottles from 1920 and up beer bottles,liquor, medicine bottles,coke , 7up bottles. Extra $50 $400 take it all
