While casually scanning the grounds of Diamond Don’s RV Park roughly 165 miles east of Dallas, David Durocher and his partner stumbled on a well-preserved Spanish Maravedis coin minted in 1661. Although this coin’s specific provenance remains unknown, true “Maravedi” coins date as far back over nine centuries. By the 11th century, Christian rulers across Portugal, Castille, and León had adopted their own variants known as morabitino or maravedí. According to the assessment of Durocher’s fellow coin collector, the Spanish 8 Maravedis find is likely worth around $5.25 in today’s currency. But even before knowing its worth, KLTV noted that RV park owner Diamond Don himself, Don Rainey, congratulated the coin’s discoverers and agreed to the age-old “finder’s keepers” rule.
