[SERVICES](https://lonemountaincoin.com/learn-more-about-our-services/) • SHOWROOM APPRAISAL WORKFLOW # What to Expect During Your Visit Whether you’re bringing in inherited banknotes, a rare coin collection, or an estate hoard, we sort, assay, and price everything right on our showroom counter in plain view while you watch—never taken to a back room. IN-PERSON APPRAISAL PHILOSOPHY ## Lifetimes of Collecting Handled With Total Transparency Many of the collections brought into our North Scottsdale showroom represent decades of dedicated acquisition, or have been passed down across generations. Our senior appraisers understand that bringing valuables into a coin shop can feel daunting if you don't know what you have. From the moment you step through our doors, our process is entirely hands-on, educational, and open. We never take your coins out of sight into a back office. Everything remains directly on the evaluation counter in front of you while we sort, test purity non-destructively, and explain the real market data driving every quote. ✓ **100% In-View Handling:** Your items never leave your sight. Every coin, bar, and bill stays on our evaluation counter right before you. ✓ **Zero-Obligation Appraisals:** All verbal valuations are completely free with zero sales pressure. Take your time to decide. ✓ **Immediate Cash Settlement:** If you choose to transact, receive immediate payment via cash, certified cashier's check, or direct bank wire. THREE-STAGE SHOWROOM PROTOCOL ## How We Evaluate Your Collection Right in Front of You No blind appraisals, no waiting days for answers. From the moment you arrive, we walk you through our scientific grading, weight verification, and market pricing methodology. PHASE 01 • WELCOME & INITIAL SORTING ### Step 1: The Initial Sort: Spreading Things Out Most collections are an eclectic mix of silver coins, raw collector pieces, vintage paper currency, and modern bullion. We start by spreading everything out across our evaluation counter right in front of you. This hands-on triage separates items priced strictly by precious metal weight from pieces that carry rare date, mintmark, or condition premiums that require deeper numismatic study. ✓ **100% In-Sight Handling:** Your collection never leaves your line of sight. Everything remains directly on the counter before you. ✓ **Systematic Categorization:** We group items by denomination, metal type, strike era, and certification status. ✓ **Educational Walkthrough:** We explain what makes each category unique and why certain pieces command collector interest. PHASE 02 • BULLION BASELINE ### Step 2: Pricing the Silver: Establishing Market Baselines For items tied directly to precious metals markets—such as bulk Constitutional silver dimes, quarters, and half dollars minted before 1965—we figure out a solid mathematical baseline. We calculate exact base metal weight using live market spot feeds and current collector demand. We separate common circulated silver from higher-grade or key-date pieces that deserve a closer numismatic look. PRECIOUS METAL BENCHMARKS APPLIED 90% Constitutional Silver (Pre-1965) 0.715 oz pure / $1 face 40% Silver Halves (1965–1970) Net fine silver weight .999 Pure Bullion (Rounds, Bars, Eagles) Live spot + premium tiers PHASE 03 • NUMISMATIC CENSUS ### Step 3: Hunting for the Rare Stuff: Census & Eye Appeal Once bulk items are organized, we carefully examine individual bills, rare coins, and certified slabs that carry high collector premiums. We don't guess. We inspect surface preservation, original mint luster, strike quality, and die varieties under high-power optical magnification. We cross-reference key pieces against surviving census population records (PCGS/NGC) to ensure their true historical rarity is recognized—maximizing your cash payout. ✓ **Surviving Population Records:** Cross-checked against NGC and PCGS Condition Census reports to identify true scarcity. ✓ **Exceptional Eye Appeal:** Clean, uncleaned original surfaces, pristine fields, and sharp strikes receive top-tier offers. ✓ **Immediate Same-Day Payout:** If you accept our offer, you are paid immediately on the spot by cash, company check, or bank wire.

The single most important rule in coin collecting is simple: **NEVER CLEAN A COIN**. Many well-meaning people polish tarnished silver or dirty gold coins thinking it will make them look better and increase their value. **The exact opposite is true.** Cleaning a coin permanently scratches its delicate metal surface and strips away its natural original mint luster (cartwheel bloom). Cleaning a rare coin can immediately destroy **50% to 90% of its numismatic market value!** ✕ WHAT TO AVOID - **Never Rub with Cloths or Towels:** Even soft microfiber causes microscopic surface hairlines visible under numismatic magnification. - **Never Use Silver Polish or Baking Soda:** Abrasive chemical compounds permanently strip original surface metal and ruin the coin's grade. - **Never Use Acidic Cleaners or Vinegar:** Acids dissolve microscopic metal flow lines created during the original mint strike. ✓ WHAT TO DO INSTEAD - **Leave Dirt, Tarnish & Patina Intact:** Natural age toning and discoloration are prized by collectors and act as proof of authenticity. - **Bring Them in Original Holders:** Jars, plastic bags, cardboard envelopes, albums, or old boxes—bring them exactly as you found them. - **Let Our Experts Evaluate Them Safely:** We inspect every piece in its natural, unaltered state and provide free, zero-pressure valuations. NON-DESTRUCTIVE LABORATORY VERIFICATION ## In-House Scientific Testing Equipment We never use destructive acid testing or metal filing that defaces your valuables. We invest in the industry's most advanced non-destructive metrology tools in our Scottsdale showroom.

Get straightforward, honest answers about how evaluations work, what to bring, and how we calculate offers. Call: (480) 878-1760 **Do I need to clean my coins before an appraisal?** Please, absolutely **never clean your coins**. Altering the original surfaces destroys their exceptional eye appeal and can severely diminish their numismatic premium. We strongly prefer to evaluate your pieces exactly as they are, in their original, natural state. **What is the difference between raw and certified coins?** **Raw coins** are unencapsulated pieces that have not been professionally graded. **Certified, or slabbed coins**, have been authenticated, graded, and sonically sealed in a tamper-evident holder by a major third-party grading service like PCGS, NGC, or CAC. Both hold immense value, but certified coins carry established market population benchmarks that simplify valuation. **How long does a full professional appraisal take?** The timeline depends entirely on the size and complexity of your collection. A small box of Constitutional Silver or a few bullion bars might take just **10 to 15 minutes**, while evaluating a massive, multi-generational hoard of rare key dates requires careful, methodical examination. We never rush the process, and we keep you informed every step of the way. **Will I receive an offer the same day?** **Yes!** Once we complete our thorough evaluation, we provide a transparent, zero-pressure cash offer immediately. We walk you through exactly how we arrived at our figures, ensuring you have all the information you need to make a confident decision. If you accept, payment is made on the spot by cash, company check, or bank wire. **What if I inherited a collection and don't know where to start?** This is one of the most common reasons people visit our showroom. Don't worry about organizing, cleaning, or sorting anything. Simply bring the collection in as-is. Our team will sit down with you, explain what you have, categorize it openly, and separate the common items from the rare treasures.
