    As a kid I used to drool over all the old silver shipwreck coins from the Dutch VOC wrecks off the West Australian coast. The West Australian Maritime Museum have heaps from these old wrecks.

    While in Amsterdam last year I visited the Rijksmuseum to see Dirk Hartogs 1616 Pewter Plate. The previous occasion I was in Amsterdam, the Dirk’s plate was on tour in Australia!

    While in Amsterdam, I visited a coin shop and bought a few sovereigns and was taken by a big silver Rijksdaaler minted in Overijssel in 1620. I bought it but later was concerned it may not have been silver. The coin did not ring as most silver coins do. The coin did have a small crack in it’s edge. It’s the coin shown in my avatar.

    Today I dropped into Bullion Now in Melbourne. I took my big Rijksdaaler with me in the hope to have it XRF’d. Ruben from Bullion Now happily tested it.

    This was the result:

    Ag. 93.56%
    Cu. 5.92%
    Pb. 0.326%
    Au. 0.19%

    it appears my coin is legit. I didn’t expect the silver content to be so high or for it to include Lead and Gold!

    Many thanks Bullion Now for testing my only coin!

    66rounds, yes, the early Rijksdaalers are supposed to be .885 fine silver.

    The XRF outcome of this one was a real surprise!

    It was about 1972 when Allan Robinson Co founder of the Dutch wreck "Guilt Dragon" got me into diving as a youngster. He showed me a hoarded of silver he took from that wreck back then, & since that day I fell in love with it and have always pursued silver ever since. :D.... SS member Serial knows the passion don't ya bro

    Jason1, my Rijksdaaler weighs .915 toz or 28.45gm.

    0.915 x 0.9356 = 0.856 toz of Silver. This lines up with the Wiki entry for early rijksdaalers.

    I thought it meant the coins were supposed to be 0.885% silver but it must mean the coins contain 0.885 of a troy Oz of Silver.

    Given the wear on my old coin, the weight is pretty close to what it should be.

    Hopefully there is someone more knowledgeable on these old Dutch pieces on the forum.

    BTW, I think it cost me about €100. No idea if it was a good deal, I just wanted it. :)
