Who is a challenge coin collector would you purchase a challenge coin knowing it will benefit a non-profit organization owned by a Veteran?

Don't collect challenge coins - I earned them. I will be more than happy to donate funds - but keep the coin.

I have roughly 75 coins to my collection.

History of the challenge coin
Manny different version have been put forth, one is from a wealthy pilot in WWI but, my personal favorite was told to me by the Ship’s Boatswain when I was a young lad sailing the Mediterranean sea for the first time.
Challenge coins date back to the day of sail when pirates and privateers would often melt down their loot and coin common denominations with their own seal because they had no money sanctioned by a crown, the first because of his trade and the second because they often operated too far from home to maintain enough in their coffers to pay for the necessities of a long voyage. Often these coins were used to pay the ship’s crew. These crew members, most often the Men at Arms (Marines), would find their way to the local pubs to spend some of their spoils. When it came time to pay they would slap the coin down on the old rickety wooden bar and as they pulled their hand away the other patrons would peer over to see what seal their coinage boar. Mostly to see the crown, needless to say someone with a British coin in a bar full of Spanish or French sailors normally ended in a brawl. Yet in some cases a crest other then the crown would be revealed. No doubt Blackbeard’s crest was the Jolly Rogers and would licit fear in the other patrons. Coins from the privateer Bonhome Richard would no doubt illicit admiration for the Navy of the young country standing up against the British Empire. It was not uncommon for those patrons to show respect for those sailors by buying them rounds so as to loosen their tongues and hear the tails of heroism on the sea the bearer had experienced.
