ACH, lm lucky guy who has, in diameter of 5-6 kilometers, over 40 fields with signs of celtic and roman settlements..
Great coin find! Unfortunately, where I live there is zilch chance of finding anything ancient/medeval..... Maybe, if you where in Quebec City (Old Part) you might find older French coins from Louis XIII/ XIV/ XV. However, back home in Germany you could if very lucky find some Roman coins, with the ultimate dream of unearthing a clay pot with 20 or more mint state Postumus aurei and keeping it secret
