Over the years various people have come to me saying they are selling platinum, how do they do it etc. The source was said to be from a Japanese cargo ship WWII lost off Masbate. As you say there are plenty of scammers and it is very dangerous business, especially in Philippines. As the bars or objects are always large the Specific Gravity can easily be calculated in your back yard. A spring balance, or bathroom scales, water and a bucket that overflows into a larger container. Weigh the water displaced and compare with the dry weight. or simply weigh in air and then weigh in water (archimedes) and eureka you find the Specific Gravity. This will tell you if it is stainless steel or platinum or palladium. Look up Specific Gravity of these on the internet. I have been shown 98% iron and also Titanium . If you want confirmation send a tiny sample (2.5 grams) off to a recognised Analytical laboratory for an XRF scan.. Tell the lab that you want to know approx composition of metals. The best place I know is Sheffield Assay Office, Guardian's Hall, Beulah Road, Hillsborough, Sheffield, S6 2AN, United Kingdom.

If I had any gold or platinum for sale I would take it immediately to the Treasury at Banco de Oro in Manila, (they mint coins there aswell) . They will take their cut and in two days (after they have done their own analysis) you will get your money. The amount your receive will be the proper rate and everything is then done legitamately.
