Generale Alphonso Di Paola- what medals did he receive in WW1
One of the medals was the Victory Medal. Awarded to anyone who was in Britan or any of her colonies surving at the time.
That is a vague Question as you did not specify a country or type of medal. So a vague answer would be from $15 to $2000. Some medals were made and issued in the Millions so they are not worth much. If the medal is engraved with the soldier's name, then it would be worth more. If the collection includes all the medals earned by one soldier AND some medals are for bravery or for a rare area of service, then the value goes higher. British issued campaign medals that were for service in a specific region and some are more rare than others. Since the US Marine Corps was not very large, some of these medals can be valuable. Also, an older Veteran can order his medals and they could have been issued 30 or 50 years after the war. These may not be worth as much. The Germans issued about 3 Million of their Iron Cross 2nd Class medal. It is worth about $40 to $70. But a similar Iron Cross issued by the Nazi in WW2 will be worth $75 to $125 or so. There is a more demand for Nazi medals than WW1 medals.
