The coin you sent the link for sold for $200 in 2002. Looking at more recent auctions, I see this type of coin selling for as low as $165 for a copy in better condition than the one pictures and a high of $450 for one in worse condition.
You can find them other examples for sale at www.vcoins.com
and check past auctions at www.coinarchives.com
. Use the search functions on both websites with the words "salamis shield" and you will get the same results that I did.
