I need to Select 1 row from each row/pair having Max(PriceID) and return 1 row if only 1 row is found (non-pair).

For example:
   1400      OH              Price List 4      101              Hammer       26              12.50      2014-12-1
   1400      OH              Price List 4      320              Pliers       10                9.25      2014-12-1
   1400      OH              Price List 4      221              Drill               30              39.99      2014-12-1

[Table Data]
ListID	State	ListName	Code	Name	 PriceID	Price	  Date	
1400	OH	        Price List 4	101	        Hammer	 26	        12.10	2014-12-1	
1400	OH	        Price List 4	101	        Hammer	 24	        12.20	2014-12-1	
1400	OH	        Price List 4	320	        Pliers	 10	          9.25	2014-12-1	
1400	OH	        Price List 4	320	        Pliers	 8	          9.15	2014-12-1	
1400	OH	        Price List 4	221	        Drill	         30	        39.99	2014-12-1
