Ahhh, but we have your T' net "today's finds" show & tell posts as the "papertrail". Plus I have video of you in the park digging those clad quarters and dimes. Tsk tsk.
Ok, if you never cash in that clad, and never sell your key date stuff on ebay (we're watching your ebay account), then you're fine. Yes, not till sold or used ("realized") does it qualify as income I think .
My wife is a tax accountant and she says it's income when you found it, no selling involved.
Like any income the IRS doesn't care what you do with your income. Spend it, save it, throw it away, doesn't matter.
Very much like gambling. You owe it when you win it.
Income is "realized" when you control it.
As far as a paper trail concerning something like gold, it's there. Dealing with any legitimate business they in all likelihood will follow the rules. It would be an expense on their Schedule C. All those expenses are backed up on paper in case the IRS calls.
All these problems on how to get around the money issues is why money laundering was created. Most laundering involves a net loss.
Small amounts of money or anything worth money aren't usually a problem but put your mind on how to deal with large amounts and it can be a real heads scratchier. Rule #1, never use a legitimate institution like a bank account.
Don't use cash for transactions as it raises flags these days of plastic (Few expect to get paid in cash anymore.) Cash is often viewed as suspicious.
Wife and I rode over to buy a mattress. We had our leathers on of course and when she laid out $1300 in cash the manager got all frustrated like what to do if he had to make change.The store had next to nothing as far as cash went.
I can imagine his stories about these two bikers came in and laid out all this cash etc. Like where did it come from etc.
Just saying cash was expected once but now it draws attention easy. Especially if a person or class of people are a bit outside the norm.
So the manager asks "So, are you a biker?" I says" No, I'm a motor cycle enthusiast". He got a weird expression and let it go.
