@Ekaeoq I would negotiate on the case, movement, and strap pricing. Very cool 👌

@landforce It was big news in my area lol. It was always a little sketchy there, nice property though

I always hated was the slow speed of taking perfect photos and then still creating the the listings. So I built a tool that does both for you.

Here's a quick run-through of how it works. Try it free at https://t.co/Q755UJZGkQ (no signup needed to clean your first photos) eBay listing is a paid feature, photo cleanup is free to try.

CoinRectify takes your regular phone photos, cleans them up to a crisp white background, and then writes the full eBay listing for you: title, description, category, and item specifics, all straight from the photo. When you're done you export an eBay CSV and upload the whole batch at once.

What it does:

• Removes the background and squares up every coin, no Photoshop or light box needed
• Identifies the coin and writes a keyword-rich title, description, category, and item specifics
• Handles front and back together, and whole batches at once
• Exports an eBay CSV with the cleaned image URLs already in it
• Adds stock numbers and your own logo if you want them

Who it's for:

Anyone selling coins on eBay, whether you're a collector clearing out duplicates or a dealer listing in volume.

If you want to add Google and Apple login to your website, you should. It's not hard, and it doesn't take very long.

You will need a Google Developer account and an Apple Developer account.

You will need to click some stuff and type some stuff.

AI can walk you through it, and it should take less than an hour for both, start to finish.

I did Apple a few days ago and Google today for my web app https://t.co/m92m1MT4xL which gets coin images looking good for eBay or any other online platform.

Also on a paid tier, you get AI eBay listings, which saves a LOT of time. 5X minimum time savings.

Free to play with the photos if you're into coins!

Our app https://t.co/XdX3HuyGbd used to take 10-30 seconds to cold load. We were sure it was our code. It wasn't. Here's how we got it to instant.

First clue: the server was fast. ~130ms to return HTML, sitting idle and healthy during the slow loads. Whatever was slow was in front of it.

It was Streamlit. Every load pulled 47+ JS chunks and opened a WebSocket before rendering a thing. Great for a prototype. Rough for a product with paying users.

Fix: keep the whole Python backend, swap only the frontend. FastAPI + HTMX + server-rendered HTML. Models load lazily and warm up in the background so nothing heavy runs at boot.

Cutover with zero downtime: ran old and new on the same database, then pointed the domain at the new app. Voilà. Now it loads instantly.

We didn't add anything new. We just deleted what was slow.

Happy coin selling!

@Dave_Geoghegan_ @starter_story At 5k, he has 20-21 clients, manageable for one guy. Could build out SOPs and have a team, but 🤷‍♂️ it’s a good simple life with no team.

Share with your friends who sell coins. Most of them can benefit from the hours saved.

Coin Rectify now does the whole pipeline. It crops your coin photo onto a clean square canvas (logo and stock number optional), then drafts the full eBay listing with title, description, item specifics, correct eBay category, the works.

I just timed myself. From "haven't taken photos yet" to 10 eBay drafts in 5 minutes. That's 30 seconds per coin to draft. Add another 30 seconds per coin to verify the AI's work and fill in what it can't see (condition, mint mark, price, SKU), and you're at 1 minute per coin from raw inventory to a published listing. About 60 coins per hour if you keep the pace.

A manual eBay listing done well takes 8 to 12 minutes per coin. That's photos, editing, title research, category, description, item specifics, all of it.

Coin Rectify is 8x to 12x faster.

Title and description are SEO-optimized so your listings actually show up in eBay search. Cleaner photos + searchable titles = more views, more sales, higher hammer prices on auctions.

Plans:

Free: 50 photo crops per month, no AI listings. Make an account, try the photo cleanup. Always free.

$29 AI Pro: 100 AI listings + 300 photo crops per month. About 17 hours back every month at 10 min replaced per listing.

$79 AI Business: 500 AI listings + 1,500 photo crops per month. About 83 hours back every month, basically two full work weeks. Just 16¢ per listing to skip 10+ minutes of work each.

The plans cover themselves on time alone after just 9 listings on Pro or 24 listings on Business. That's before counting any extra sales you'll get from sharper photos and better-ranked titles.

If you list coins for a living, the math is obvious. If you're a hobbyist, the Free tier already saves your weekends.

For my coin bros, list faster, get higher bids with nicer photos.

[Steven Sinatra @sln4tra]

@__el__toro__ It’s ok. Depends on the usage. If it was used on a part of the product that is typically ignored, it could be considered luxury. If it is the main surface, probably not
