✅ Do
Weigh everything. A cheap gram scale settles most arguments — price by the actual weight, not the seller's claim or a worn stamp.
Buy bullion near melt. Melt (weight × purity × spot) is the floor a plain coin, round or bar won't fall below. The closer to melt you buy, the safer you are.
Read dates & mint marks first. One key date — a CC Morgan, a 1916-D dime, a war nickel — can dwarf a whole lot's melt. Sort before you bid.
Test it. Silver rings (a long ping, not a thud); real gold & silver are non-magnetic; calipers catch fakes that are too thick or light.
Verify slabs & cards. Look up a PCGS/NGC cert number on the grader's site; keep sealed PAMP/Geiger assay cards sealed — cutting one kills the premium.
Check what actually sold. Use eBay's Sold filter (or the board above) — asking prices are fiction; sold comps are the real market.
⛔ Don't
Don't mix up the two prices. Never pay collector money for a melt coin, or melt money for a scarce one — know which you're holding before you bid.
Don't fall for the fakes' words. "Copy," "tribute," "layered," "clad," ".999 plated," "HGE" — all worthless base metal. Real bullion says its weight & fineness.
Don't skip authentication on big vintage bars. Engelhard, Johnson Matthey & PAMP are the most-counterfeited — verify stamp, weight & serial before you pay the premium.
Don't overpay for novelty. 1-gram pieces, mini-fractionals & copper bars run 2–4× melt — you're buying the piece, not the metal.
Don't clean coins. A wipe or dip can halve a collectible's value. Leave the patina; let a grader judge it.
Don't forget the add-ons. Auction buyer's premium (often 15–25%) and sales tax stack on top — fold them in before you set your max bid.
📐 Melt is the floor
Melt = weight × purity × spot. A bullion piece is worth at least this. "Est. value" adds a typical premium on top.
🪙 90% junk math
$1 face of pre-1965 silver ≈ 0.715 ozt. So $10 face ≈ 7.15 ozt. Fast melt without weighing each coin.
💵 Spot vs. retail
Spot is the wholesale metal price. You buy over spot and sell under it — the gap is the dealer's spread.
🧲 Quick fake tests
Magnet (real Au/Ag won't stick), ping/ring test, calipers for size, and the ice test — silver melts ice fast.
🥈 War nickels
1942–45 nickels are 35% silver — big mint mark over Monticello. Every other nickel is just copper-nickel.
🔒 Slabbed = liquid
