Embed the Coin Worth Checker on Your Site

A free coin-valuation widget for any blog, forum or news article. Your readers get realised UK auction prices on 4,700+ British coins; you get a useful interactive tool with no setup. Just paste the iframe snippet — that's it.

How to embed

Copy this single line and paste it into your blog post, forum thread or article:

<iframe src="https://mycoinage.co.uk/embed/coin-worth" width="100%" height="540" style="border:0;border-radius:12px" title="MyCoinage UK coin worth checker" loading="lazy"></iframe>

Works in WordPress (Custom HTML block), Ghost, Substack, Medium (paid plans), Wix, Squarespace, and anywhere else that allows iframe embeds. The widget is responsive and resizes to fit.

Customising the embed

The default widget is 540px tall. You can change the height attribute if you want a shorter or taller box. The widget will display fewer or more results based on screen height. A few popular sizes:

  • Compact (one result): height="360"
  • Standard (default): height="540"
  • Tall (more results visible): height="700"

Pre-loading a search? Append query parameters:

<iframe src="https://mycoinage.co.uk/embed/coin-worth?q=Kew+Gardens" width="100%" height="540" style="border:0;border-radius:12px" title="MyCoinage UK coin worth checker" loading="lazy"></iframe>

Supports ?q= (coin name or denomination) and ?year= (any 4-digit year).

Attribution requirements

None — beyond what's already baked into the widget. Every embed shows "Powered by MyCoinage" in the footer, and clicks on coin names open the relevant MyCoinage coin page in the parent window (with UTM tracking so we can see embed-driven traffic).

You don't need to credit us elsewhere or link to us elsewhere on your site, though we appreciate it if you do. The widget is genuinely free.

FAQs

Will the widget slow my site down?

No measurable effect on Largest Contentful Paint or Cumulative Layout Shift. The iframe loads lazily (with loading="lazy") so it doesn't block your above-the-fold content.

Can I customise the colour scheme?

Currently no — the widget uses MyCoinage's dark palette (navy + gold + electric blue). A light-mode variant is on the roadmap. Drop us a note via /contact if that's blocking you.

Can I embed multiple widgets on the same page?

Yes. Each iframe is independent.

What about US coins?

The current widget covers British coins only. A US widget is on the roadmap as our US catalogue grows.
