There are no gold pennies. I found this plated one recently. Yours looks like a normal one in decent condition. If it's gold (I don't see it) then it's plated, no extra value.
Mine looks more gold than picture reveals... Still learning and trying to get better pics... I like yours!!
The only gold cents known are some Indian Head cents that were struck on Gold $2.50 blanks. All from early 1900's.
Looks like a relatively untoned 1964. I suspect after he uses it for awhile it well tone browned from the repeated skin oil and salt contact.
how many do you want ? what years do you want? what denomination do you want ? one such example ==> https://www.merrickmint.com/24k-gold-plated-coins.html eBay is littered with them too.
