Okay. I think it would be reasonable assumption that Finance::Quote
returns pricing in ISO-4217 currencies. But definitely a quagmire when
faced with an issue like this one.

Which is why I posed the original question. Aside from the two of us
having this wonderful exchange of ideas, no one else stepped in to say
"Hey! I get some LSE traded stock data from AlphaVantage, and doubling
the time it takes to get quotes would annoy the heck out of me!". At
this point, the only one to raise an issue is someone that could deal
with it as is for all I care.

Alright. At some point I'll have AlphaVantage look for symbols supplied 
with an additional '.X' suffix. If it's given, divide the pricing info 
by 100. If not, leave it be. Of course I'll add info on this to the 
manpage/POD. I'll also ping AV support again. I was told they would look 
into adding the currency to the JSON returned from the GLOBAL_QUOTE API 
which would make my job a zillion times easier.

Thanks again John.
