I prefer acquiring coins this way to any other way. I could have bought the same quarter on
ebay for $5 but finding it in the wild made it far more special and exciting for me. I could have dropped a $1 into a slot machine, won $20, and bought 4 identical 1958 quarters but I wouldn't have gotten 1/100th of the rush, the excitement, the amazement, fun, joy and the awe of the sheer luck involved with finding silver in the wild. I'm also proud of myself for spotting the silver quarter right away, as soon as the guy pulled the change out of the drawer.
I imagine a casino would be a fairly good place to find silver. (As far as I know) this casino is card only and the machines do not eject coins upon winning. I assume the patrons bring their money to the counter and exchange it for casino credit (I have no idea how it works) and I would imagine that a larger percentage of these coins would potentially be collectible or old because gambling is an addiction and addictions can make one sell things you wouldn't normally sell.
I worked at a casino for a few months as a barback, hated it. The job wasn't bad (manhandling 180lb full kegs of beer wasn't exactly a barrel of monkeys) but the cigarette smoke wreaked havoc on my health. Yes, smoking is legal in casinos here...terrible law. By my fifth day, I had completely lost my voice. On top of undiagnosed sleep apnea issues it was a miracle I breathed any clean air at all. The casino lifestyle is just...odd. I can't put my finger on it but there is something strange and peculiar about the whole place. I'm glad I no longer work there.
I got to bartend for about 30 minutes a day and I would sometimes make $20 in that short time. If I could handle the smoke, I would make a good bartender.
