Remind her the money isn't lost, just in a different bank that pays it's dividends in gold, silver, and diamonds. Show her on ebay what they sell for used and then so of the pictures of what is being found. If that doesn't work, say hummmm I wonder how much all those shoes and purses cost?
Truth really is themoney isn't lost, prices on ebay proves that. You will get all your money back and then some, just on the finds if you hunt beaches much.
According to Midwest refineries website on the value they pay for gold, I have about $750 in gold sitting in my "treasure chest" if I wanted to scrap it, but I'm holding on to it for now. That is $100 short of paying for the first Excal I bought. My Whites Beach Hunter ID paid for itself before I traded it for the Sovereign GT, plus I got a real good trade in on it so I figure my Sovereign with WOT is 3/4 paid for already. I bet by fall the 2nd Excal will be close to paid for with the finds.
With beach hunting the gold adds up, that is one of the reason I love beach hunting, all the nice potential targets waiting to be found.
Good luck and good hunting.....
