Question: From a list of strings extract substrings

From a list of strings say

L:=[k$1,y$23,f$25,........]

A particular type of delimiter will their which is  common to all elements in the list the right side is always a number 

The function takes the list, and the delimiter as input

Then it outputs a list of 

Numbers which is on the right side of the delimiter 

Output will be like 

[1,23,25,...]

The delimiters could be a space 

Or 

Space on both sides of dollars

That is in understanding space should also be considered in delimiter that is anything significant
