Gold, but don't do this..........bugga

Still at Whitianga,and this time I spent the last two days at Buffalo Beach, A little bit of time spent on the lower tide line was fruitless,but moving up the beach 2 metres below the high water mark I found the G spot,an area around 2 metres wide stretching down the beach about 200 metres,I found all the bits pictured,and they are a big variety,ranging from modern $ through to the 1872 threepence with the hole in it,the old fob watch looked promising but fell to bits when I tried to free it up.

 The mans large gold ring once again shows how brittle they become after years in the salt,would you believe I had just finnished washing it,when it slipped out of my hand and landed on the lino promptly disintrigating into 4 pieces,I couldnt believe it,this is the 3rd time a ring has broken on me will cleaning it,I talked to a jeweller about it and he explained that the combination of metals break down over time due to a reaction from the salt and elements,generally on the lower rated carat rings etc.A bit of super glue patched it up to keep all the bits intact,also found a few very early bullets and lots of old copper sheathing along with old copper nails I can only guess they are from the old sailing ship HMS Buffalo that blew aground here many years ago,I went back yesterday afternoon and the beach had already started to change with the sand building up again.But I still picked up a few more coins plus two more silver rings......
