Not the most expense I paid but now worth the most. Got a 1914 CJ Marquard at small dealer in NYC for $200 some 15 years ago. Ungraded and, frankly, i didn't know then if '14 or '15 or if a reprint. Sent it away to PSA about three years later and happily found out it was 1) legit 2) a NM and 3) the highest graded. All those things still true these many years later.
