Using a coin instead of plastic pick

[MetalManiac]

BIlly gibbons' quarters are "railroaded" so they have been squashed and stretched by being run over by a train. Brian may uses a sixpence. The aussie 5c piece is a good substitute for that but a litlle smaller.

Yeah..those are good picks, they put some pretty good stress on the strings but a regular coin will chew up your strings right quick.

I've never been able to play with coins, that slippery uneven border makes me sick with its 'zzziiing' sound.
The best pick I ever played with (actually the pick I currently use) is the Dunlop Ultex 1.14, next comes the Dunlop Tortex 1.00

They DO make metal picks as well. So if you like the bright attack of metal, you can get it while also enjoying the advantage of a shape that actually works for picking strings. Personally, I'd LOVE a pick made of Zildjian cymbal bronze shaped like the 2mm Stubby that's currently ruling me.
