will higher pix give me a better effect, or is it just a gimmick? will it make any different when picturing coins?

http://www.wired.com/gadgetlab/2008...megapixel-m/On smaller less expensive compact cameras the quality is compromised by increasing pixel density on the sensor. That means less color and edge accuracy.
The advantage of many pixels is that it is possible to hold sharpness of an image when you blow it up. It also make a big difference if you are printing photos. 5 mega/pixels will make a nice 8 x 10. Typically a paper photo requires 300 dpi or better. Professional magazines want upwards to 2500 dpi. However if you are shooting shots for
ebay or a computer shot, you only need to make a photo with 72-80 dpi.
My Canon shoots huge 12 megapixel (M) photos. But when I am shooting most coins I have it set for the smallest setting, 2256 x 1504 (3.2 M). One reason I like to capture smaller photos is that the larger files are so huge they take up tons of space, take longer to load and manipulate. I find I can do great blow-ups at 3.2M as long as its for the Web.
The plus side for shooting at 12M is the Canon has a large excellent sensor and a really nice lens. I can blow up for detail and get microscopic results.
My advice for coins is that you don't need the latest and greatest to get good coin shots for the Web. (Its another story if you printing these) Better to spend the money on a good macro function, a tripod and lights.
The shots you posted look darn nice to me. Sometimes the grass is greener...
