Sounds like a good deal to me. Even if the coins are nothing he has 200 slab shells at 40 cents apiece. Retail tends to be around $1 each. So he will have some protective shells he can use for coins at aren't worth sending to the TPG's.
Except you had the right equipment to handle the situation. You surely didn't walk around with your head in the clouds.
No but sometimes all your equipment was was a porcline poker and a protective suit. I watched a training video on disarming a mine and the instructor look up and it went off under his mask and died. My favorite was the miclet(?) Rocket. Had a net of c4 on it that was used to clear minefields. Looking back i should have maybe done something thatll getme a job or something. But at the time (2006, 18yrs old) i wanted to blow stuff up and play with explosives. Lol
