What NUMISMATUM is
NUMISMATUM is a numismatic arbitrage service: it catches for-sale listings on Reddit, parses text and photos, compares the seller’s price to the eBay market, and returns BUY / WATCH / REJECTED.
Good deals disappear in minutes. Scrolling listings by hand, reading photos, and checking the seller’s ask against typical eBay sales is too slow — the service does that for you.
Four Live steps
The arbitrage chain: from Reddit WTS to lot status and alert.
Live VISION
Year from the photo
VISION reads the mint year from the coin or packaging when it is missing from the text. Text parsing splits the post into individual lots.
Live compare eBay
eBay market + melt
Seller ask vs eBay reference; for bullion — metal price too. Numbers come from the system, not the model.
BUY · WATCH · REJECTED
Status and alert
Cabinet rules → a decision per lot. Telegram focuses on BUY; the full breakdown stays in the cabinet.
Three decisions on every lot
Not one verdict for the whole post — a status for each coin or bar.
BUY — actionable by your cabinet rules and status scoring. WATCH — review in the cabinet. REJECTED — we skip it. The full breakdown always lives in the feed; Telegram gets the buy alert.
How the cabinet looks
This is the live feed in the cabinet: lots from Reddit with BUY / Watch / Rejected status.
Filters All / BUY / Watch / Rejected cut the noise. Each card shows the decision, seller ask, eBay benchmark, and margin — so you can read the call before Telegram.
What's on a lot card
Status, seller ask, eBay benchmark, and margin — all on one card.
The system compares the lot to the market and sets BUY, Watch, or Rejected. Telegram mostly gets BUY alerts; the full breakdown and action buttons stay in the cabinet.
What gets parsed
Broader than “collectible coins only.”
Coins (bullion and classics), bars and assay, stackers, constitutional / 90% silver cleanout. Art rounds and disputed raw grades are filtered out by default.
What VISION determines
A separate step after text parsing: listing links → albums and photos → mint year on the lot.
Text parsing first splits out individual lots — name, metal, quantity, and seller ask. Then VISION, when needed, analyzes photos and albums and reads the mint year on the coin or packaging. BUY / WATCH / REJECTED comes from cabinet rules and status scoring after the eBay compare — not from an “opinion” of the image.
How it works
The arbitrage chain: from Reddit WTS to lot status and alert.
Step 1
Live capture
Chosen subreddits, WTS by default — new for-sale listings as they appear.
Step 2
Lots and VISION
Text parse → separate lots with price. VISION reads the year from photos when needed.
Step 3
eBay and melt
Market reference and metal price come from the system — the model does not invent them.
Step 4
Lot status
Cabinet rules → BUY / WATCH / REJECTED. Cabinet has everything; Telegram focuses on BUY.
Why it helps
The upside, in plain language.
No need to live on Reddit all day
NUMISMATUM notices new coin for-sale posts for you. You hear about a lot while it is still live — not after someone else bought it.
One post, many coins — sorted
Listings often include an album or a list of a dozen items. The service splits them apart: which coin, which year, which price.
Decisions rest on market numbers
The seller’s ask is compared to an eBay reference (and melt when needed). The model does not invent those figures — the system supplies them. That makes it clearer whether a buy is worth it.
What a buy alert looks like
BUY — a purchase recommendation by your cabinet rules: the seller’s ask is below the eBay reference by your set margin. Telegram gets a short alert; the full breakdown stays in the cabinet. Example is fictional.
Pricing
Three clear plans. Pay in the cabinet.
Frequently asked questions
Answers for collectors, bullion buyers, and anyone comparing Reddit asks to the eBay market.
How is NUMISMATUM different from hunting coins on Reddit by hand?
The service catches new for-sale listings, parses text and photos, compares the seller’s ask to an eBay reference, and flags the strong lots. You do not have to scroll the feed all day and check every line yourself — the buy decision still stays with you.
How does the service compare the seller’s price to the eBay market?
For each separate item, the system takes the listing price and matches it to a reference from similar eBay lots. The model does not invent eBay or spot prices: market numbers come from the system. AI helps parse text and photos, but it does not replace market quotes.
What is VISION and how does it help evaluate a coin from a photo?
VISION is a separate step after text parsing. If the mint year is missing from the listing, VISION analyzes photos and albums and reads the year on the coin or packaging, so the market compare uses a dated series — not a guess across the whole post.
What items get parsed: collectible coins only, or bars as well?
Parsing covers collectible and bullion coins, bars and assay, stackers, and constitutional / 90% silver cleanout. Decorative art rounds and disputed raw grades without a slab are filtered out by default so they do not mix with liquid market comps.
What do BUY, WATCH, and REJECTED mean?
BUY — the lot looks actionable by your cabinet rules and status scoring: an alert can go to Telegram. WATCH — interesting, but data is thin or the price is on the edge: review it in the cabinet. REJECTED — by rules or stops, we skip the lot for now.
What goes to Telegram, and what stays only in the cabinet?
By default, Telegram gets the buy alert (BUY). The full listing breakdown — including WATCH and REJECTED lots — stays in the cabinet on the site, so the messenger does not turn into a noise feed.
Do I need a Reddit account to use NUMISMATUM?
A separate Reddit account is not required for monitoring: in the cabinet you pick the sections you want. You will need Reddit yourself if you want to message the seller or complete a deal on the platform.
Can I connect several Reddit sections and set my own margin threshold?
Yes. Within your plan you connect the subreddits you need and set how far below the eBay reference the seller’s ask must be for a lot to count as BUY. That way the edge threshold matches how you buy.
How does the system handle mint year when it is missing from the listing text?
If the year is in the text, it is used for the compare. If not, VISION tries to read it from photos. For bars and some junk / constitutional silver, the year is often optional: those lots are valued by metal, weight, and market without a date.
Is the service useful for collectors who buy Morgan, Peace, and slabbed coins?
Yes: dated series and slabs are parsed as separate lots with year and condition in mind. It also helps buyers of modern bullion and constitutional silver — the parse chain is the same; year and stop rules differ by lot type.
How can I see a demo without signing up, and how do I connect my Telegram?
The public group t.me/NUMISMATUM shows Live Feeds from live Reddit channels. After you start a subscription in the cabinet, you create a bot, enter the token and your chat or group ID — and your BUY alerts start arriving there.
Who is NUMISMATUM least suited for?
The service is built for people who regularly hunt for strong lots and compare them to the market. If you buy a coin rarely “for the shelf” and do not watch market price, there is little benefit — picking by hand without monitoring is simpler.
