Okay, sorry for the hold-up. Yesterday I was at a solar-panel convention, followed by supper and wide screen TV showing the Portugal-Germany game live. Now, if anyone might be interested in digging for old coins, there's an area at Sinclair park where there used to be metal grandstands and where coins used to drop from fans' pockets. I know it's just small change, but the coins date back to the '30's '40's and '50's. Which means that you can find some silver coins as well. That's where I started my personal coin collection when I was a kid. I now have over 4700 coins from all over the world. I looked at google maps and it looks like there is a new grandstand right in the same location, but I'd check a bit further east. Another factor would be that maybe when they built the annex building nearby, they might have dug up the area, ruining what was underneath.
