Historic prices of Comex Gold and CBOT Gold?

Can someone tell me why the May 2006 high price of the continuous GC contract is $732 while the continuous ZG for the same dates is at $801.60? I know they don't trade tick for tick but those highs aren't even close. Am I missing something.
Thanks.

 

?......carrying charges? You're comparing May-2006 with February-2008? That's probably it.

 

Are you using Tradestation? It seems to be isolated to tradestation(unless you are using something other than tradestation) I have yet to figure it out, but it looks like a bad data point.

 

Bingo! I am using TradeStation. Thanks.


EDIT: Here is another source showing 2006 high under $800.
