Extract Currency from Sec id

[bubblyjai1982]

Hi All

I'm trying to extract the currency from sec id using regex tool but not able to extract only currency.

I have differentiated the alphabet and date using the expression ([[:alpha:]]+)(\d+) but from alphabet i want to pull only currency which is not at constant place in sec id.

I have attached input data and also required output.... 

Kindly assist 

Thanks in advance
