G.C., & has been graded by PCGS, considered a conservative TPG company. Now ask yourselves if this were an ancient Roman coin how would you grade it ? Pictured below the Wass Molitor $10 gold coin is an ancient Roman coin I've posted a number of times for comparison. Some collectors might scoff at this comparison , however, I believe it's legitimate. The Wass Molitor $10 coin is a "sea salvage" coin that has, without doubt, been cleaned. The Roman solidus is most likely a "burial" coin that has, without doubt, been cleaned. Many collectors of ancient coins see no point in grading them, but I find grading of ancient coins can be helpful especially if strike and surface are considered .
