Changing two columns on a table into various alternatives

I kept going around in circles on Friday, as the values are stored as strings (because I want to put AUD $, USD $ in front of them instead of just a number) it didn't work as I expected. 

It may be that I could unpivot the columns (so that I get multiple rows for each product with each currency line, as opposed to one line with all currencies) and approach it from that way, but I ran out of time on Friday for what was a 'nice to have' rather than 'must have' feature.
