Lookup or find in excel help

Hello,

I have 2 data sheets sheet one contains my Master list of items by number
Row 1 Column 1: 453658
Row 2 Column 1: 839565
Etc
my second sheet has the information I want to get to:

Row 1 Column 1: Gloves 453658A Black , Row 1 Column 2, $4.99
Row 2 Column 1: hat 839565 Pink , Row 2 Column 2, $8.99
etc

I want to search for 453658 and it returns me the $4.99 ignoring the rest of the information in that box so I end up with
453658 $4.99

The closest I have got is using a lookup formula but this only works if the data in both column 1's are exactly the same.

=VLOOKUP(A1,Sheet2!$A$1:$B$50000,2,FALSE)

Please Help

Paul
