Subset and combine elements of a list

I have a list of data.frames that looks like this: 

...................................    
   $ 97 :'data.frame':  3 obs. of  2 variables:    
     ..$ row: int [1:3] 97 97 97     
     ..$ col: chr [1:3] "0" "0" "0"    
   $ 98 :'data.frame':  3 obs. of  2 variables:     
     ..$ row: int [1:3] 98 98 98      
     ..$ col: chr [1:3] "0" "0" "0"      
   $ 99 :'data.frame':  3 obs. of  2 variables:    
  ..$ row: int [1:3] 99 99 99
  ..$ col: chr [1:3] "0" "0" "0"

I would like to subset only $ col rows and combine that in this way: 

............   
97: 0,0,0     
98: 0,0,0     
99: 0,1,0

Thank you in advance
