Tried google, bing and yahoo. all I can find is current exchange between countries.
If what i found online is correct it is about $177,300 i found this formula on wikianswers (its in the source box) hope this helps
Somewhere in the neighborhood of $170,000 to $200,000 according to inflation tables which are not too accurate at all. But if you had that $7500 in circulated 1900 gold $5.00 gold pieces it would be worth about $517,000 today. If they were uncirculated it would be worth $675,000.
