Already fails the rule at starting bid — avoid
No reliable comp — do not bid blind
- 710808 iFLYTEK D01 translator: no US eBay used sold listings at all. Cannot value.
- 710844 Assorted incomplete AirPods lot: parts-value only, no comp.
- 502122 / 502123 "Authenticated" 925 sterling ring / bracelet: melt value only, not verified.
- 502126 / 502127 / 502128 "Various Jewelry" ×3: too vague to comp.
- 706579 8-bag lot · 710802 45-wallet/purse lot · assorted electronics lots 710809, 710810, 710796–710803: vague bulk lots — inspect in person first.
- Apple charger lots 710795, 710818, 710827, 710828, 710834: not comped (used ~$25–35 likely, unverified).
- 710815 Gucci 36" belt + Gucci bag: max $25 on $120 comp, BUT counterfeit risk is high with no papers. Only if you can authenticate in person.
Caveats
- All figures vs starting bids; auction goes live Mon 8am ET — bids will rise. The max-bid column is the hard ceiling.
- 18% premium assumed; cash/wire drops it to 15% → max bids rise ~2.5% (e.g., Garmin $148 → $152).
- Everything is lost & found, sold as-is, untested. Big risks: iCloud-locked Apple devices = bricks; dead batteries; counterfeits; missing parts.
- eBay seller fees (~13%) NOT deducted — net margin is thinner than gross.
- Top 3 by dollar margin: Garmin Fenix 8, DJI Mini 4 Pro body, MoonSwatch.

| # | Item | Ask | Location | Resale | Net | Notes |
|---|---|---|---|---|---|---|
| 1 | Kubota F-Series 4WD diesel mower w/ enclosed cab | $3,000 | Nashville (23 mi) | $8,000 | $3,810 | Best play by far if model/hours check out; pickup after Oct 15; 18-yr seller, no red flags |
| 2 | Kubota RTV500 UTV | $1,250 | Jackson (45 mi) | $3,250 | $1,428 | Runs/drives but rough: soft floor pans, bad shifter cable; seller 4.7★/27 |
| 3 | Husqvarna 72" commercial zero-turn | $1,500 | Kalamazoo (13 mi) | $2,750 | $792 | Fresh 26hp Kohler (~200 hrs) on 2,000+ hr chassis; best seller in scan 4.8★/550 |
| 4 | 1996 Kingfisher 19.5' bass boat + 225hp Evinrude | $3,500 | Hastings (22 mi) | $5,000 | $700 | Verify motor compression + transom/floor rot (wood-composite hull); seller 4.8★/105 |

Thin or conditional
- Honda EU3000is generator, $650 (Homer): net ~$170 — small dollars, plus one "possible scammer" review on the seller.
- 2008 F-150 XLT 110k mi, $7,500 (Portage): nets −$205 after fees — only works as a fee-free cash resale.
- 2011 F-150 261k mi, $5,000 (Kalamazoo): net ~$120 — only if negotiated to ~$4,500.
Excluded — no margin or red flags
- 2014 F-150 247k mi, $3,900 (Battle Creek): thin margin + seller has "damaged vehicle not described" reviews.
- Aluma 4x6 trailer, $1,800 (Marshall): ask at/above resale — only works near $1,100–$1,200.
- 1999 Bobcat 320 mini excavator, $12,000 (Coldwater): priced at top of a thin market, no margin.
- Ram 1500 diesel (needs motor), JD 350C (busted rod), Bobcat 743B (unknown hours, smokes), Rhino 700FI (fees kill it), Kubota BX2200 (overpriced), JD 650 (inconsistent pricing).
Caveats
- No sellers contacted — every pick needs in-person inspection: hours, mechanicals, title, rust/rot.
- The 13% fee assumption drives the math; fee-free local cash sales improve every figure by ~13% of resale.
- Total theoretical net across all 5 picks: ~$7,375, before negotiation and inspection.
