[SG2] an odd idea for figure basing

Just an odd idea (somehow, Mr. Beast must 
have infected me... odd ideas are usually his 
forte). 

I base my SG2 figs on pennies. Works well. But I 
thought an interesting option might be to try to 
acquire appropriate low value coinage from 
each realm and base the figures accordingly 

(ie NAC on Canadian and US Pennies, maybe 
some British Pence if they are big enough). 

Is this idea feasible? It'd be kinda cool to turn 
over my OUDF to the Oz/NZ equivalent of a 
penny (which might well be a penny!) or to flip 
over my NSL and find pfennigs or whatever the 
appropriate coinage is. 

My one fear about this idea is that some 
nations (Netherlands come to mind) use coins 
so darn small I'd probably have to go to a fair 
value of coin to manage. 

Anyone care to suggest appropriate coins for:
1) NSL
2) OUDF
3) NI
4) FSE

Of course, the KV are gonna be a b*tch to get 
coins for.... (unobtainium kopins are hard to get 
here in Ottawa). 

:) 

BTW - If this is a federal crime of some sort in 
your area, my apologies. Far as I've ever been 
able to determine, it is the only _valid_ use for
