Some high (in my opinion) prices on EMs were realized on ebay this week. These are all under SOLD LISTINGS on ebay, auctions ended since 3/18.
$1,849 - Gottlieb Volley
$2,995 - Williams Grand Slam Baseball
$5,495 (best offer was less) - Gottlieb Square Head
$1,600 - Gottlieb Diamond Jack
$1,995 - Gottlieb Soccer
$2,695 - Bally Rocket III
$2,975 - Chicago Coin Hi-Flyer
$2,950 - Gottlieb Football
$2,250 - Gottlieb Dancing Lady
I looked back a couple of weeks, and didn't notice other EMs going for these prices.
