This could be a wide open conversation. I just lost a bid on a Mcmillen basket weave (went for $65 I bid $60 Im on a basket kick).. How does a person figure prices for older stamps? (Mcmillan, Hackbarth, etc etc etc). I look on auction groups on FB, but never sure what to bid? Should I have went higher on the McMillan basket?. Anyone have a sheet or website to guide a person? Thanks
