Just be mindful, two of the sales you think went in the '$1600 range' did not.   This one:   http://www.ebay.com/itm/151546971810   Which shows as ending at $1600 was actually sold at a best offer of $1400   And this one:   http://www.ebay.com/itm/141466670430   Which shows as ending at $1650 was actually sold at a best offer of $1300   The only sale to reach over $1600 was in October:   http://www.ebay.com/itm/311150248804
