Ted,

What platform are you using? I have got larger limit for my 32 bit system.

PC, 32 bits, architecture x86, Intel Pentium 4 processor with HT 
(Hyper-Threading) technology and Microsoft Windows XP SP2 (Service Pack 
2), Mathematica for Windows versions 5.2 and 6.0.1.

In[1]:= $Version
InputForm[$MaxNumber]

Out[1]= "6.0 for Microsoft Windows (32-bit) (June 19, 2007)"

Out[2]//InputForm=
1.9202246726923565854204690606`15.954589770191005*^646456887

In[1]:=
$Version
InputForm[$MaxNumber]

Out[1]=
5.2 for Microsoft Windows (June 20, 2005)

Out[2]//InputForm=
1.9202246726923565854204690606`15.954589770191005*^646456887
