As Logan and Tuxedo pointed out, selling now entitles you a tax loss. Last time I checked, you can deduct up to $3000 in losses from your normal income (job income). In the $70k range, you'd save about 25% of that in taxes, recouping $750. So here's one idea: sell at least $3000.
FWIW, the logic you have been using is what I call "normal investor logic", which leads to thoughts like "I'll hold until it goes back up to even." Understandable, but...investing is a weird game because normal often doesn't work so well.
One key thing to know is that if your emotions are normal, it helps to get the emotions out of the mix to the extent possible, and instead use some reliable system - preferably one that works with little effort. I believe Mr. Money Mustache recommends 2/3 in low cost stock funds (eg, through Vanguard) and 1/3 bond funds (same), or similar accounts through Betterment. Regardless of what system you adopt, the benefits come from sticking with it. So I support the posts of the other commenters who suggested establishing a plan, Investment Policy, etc.
One final comment since you are new at this. Metals vs stocks vs bonds vs cash vs real estate all have their day in the sun. When they're hot, a host of "experts" will issue portfolio recommendations featuring a large portion of the era's hot asset class. Then they drop off; after a while, only a small group advocates it heavily. FWIW, I've been watching investments for 30 years and buying for 20 (oops! 10 year mistake!) and the eras when metals win seem few. Regardless of your specific choice, I applaud your thrift, and the fact you are investing aggressively when young. Mr. Money Mustache doesn't recommend precious metals as far as I can tell...but times can change and you call the shots.
