Ignore colour and flare and all the pretty bits that come later when refining the image - these are just design concepts for consideration as a basis for the final design:
Must say that out of all the design concept this satisfies my sense of style the most, maybe 'cause i don't like metallic colors that much in general.
Hope this refines to something else than the spectrum of silver/iron/gold.
Also not so fond of overuse of rounded corners on many of the other designs F-letters.
Even tho' these are also pretty curly... but it's a linear curl, not rounded off!
Maybe this is 'cause it reminds me how THEY round off my fiat money.
The EUR-spinoffs were also amusing for being so close to home, euro being my coin of choice when it comes to shopping necessities like toilet paper, cat food, coffee and cigs.
BTW/FYI even though we use euros in Finland we don't have the 1snt & 2snt coins in use at all, that gets me rounded up.
DISCLAMER: IMHO
