Sept 23 (Reuters) - Copper prices fell on Wednesday as a stronger U.S. dollar made greenback-priced commodities less attractive for buyers using other currencies.

Three-month copper on the London Metal Exchange fell 0.6% to $6,739.50 a tonne by 0200 GMT, while the most-traded October copper contract on the Shanghai Futures Exchange dipped 0.2% to 51,650 yuan ($7,609.35) a tonne.

The dollar held onto gains against major currencies on Wednesday, supported by positive U.S. economic data and concerns about a second wave of coronavirus infections in Europe and Britain.
