Best Electronic Shelf Label System for Coin Shops: PriceTaglet vs. SoluM vs. MinewTag

Coin shops have a pricing problem most retailers don't: the value of their inventory changes all day, every trading day. A one-ounce gold coin, a roll of 90% silver dimes or a 14K chain is worth more or less as the market moves. Electronic shelf labels can fix that, but only if the system can follow the market.

This guide compares three ESL options a coin shop might consider: SoluM, MinewTag and PriceTaglet.

Third-party prices come from public reseller and marketplace listings in October 2026 and change often. Confirm before buying.

What a coin shop actually needs

Before comparing brands, it helps to list what matters in a precious-metals store:

1. A live market price source for gold, silver and platinum.
2. Formula pricing: metal content x spot price + premium, recalculated automatically.
3. Tags that read well in display cases under bright lighting.
4. Owner-friendly setup without an IT department.
5. Clear total cost: tags, gateway and software, including what happens after any trial.

Most ESL systems are designed for grocery and big-box stores, which handle items 2 to 4 well enough but leave item 1 to you.

Where each system shines

SoluM is built for scale. Its Newton Gateway supports tens of thousands of labels, and its lineup covers almost every size, color and environment. If you run many locations with an IT partner, it's a proven choice.

MinewTag is easy to get your hands on. Demo kits and gateways are sold through electronics distributors and marketplaces, and a demo kit with eight tags and a gateway has been listed for about $599. It suits tinkerers and developers who want to build their own setup.

PriceTaglet is the only one of the three built specifically for precious metals. Tags are configured by metal type, weight and karat, a live spot feed covers gold, silver and platinum, and the hub recalculates and pushes new prices when the market moves.

The hidden work with general-purpose systems

With SoluM or MinewTag, connecting tags to the gold and silver market is a project you take on yourself:

1. Choose and pay for a market data source.
2. Decide which benchmark to follow. The LBMA sets its gold price twice a day and its silver price once a day, while spot prices move continuously.
3. Build or buy software that recalculates each item's price from its metal content and premium.
4. Push those prices into the ESL platform through its API.
5. Keep all of it running.

For a chain with developers, that's manageable. For a single coin shop, it's usually the reason digital tags never get past the demo kit.

Why an all-in-one system matters

PriceTaglet makes both the tags and the software, and the price feed is part of the product. That gives a coin shop:

• One vendor for hardware, software and pricing data.
• One dashboard for items, formulas, markups, overrides and battery levels.
• No integration project between a market feed and a label platform.
• A U.S.-based team to call when something needs attention.

The bottom line

If you're a large retailer with an IT team, SoluM is a strong general-purpose platform. If you're a developer who wants to experiment cheaply, MinewTag hardware is easy to buy. If you run a coin shop, bullion counter, jewelry store or pawn shop and want prices that follow the metals market without building anything yourself, PriceTaglet is designed for exactly that job.
