Put the melt calculator on your site

The same calculator as our melt value page, sized for a club page, a shop's website or a blog post. Paste one snippet and it's there.

Free to use

For clubs, shops and blogs

Free. No sign-up, no ads, no key.
It prices 37 common US and bullion coins, or any metal by weight and purity, at current spot. It shows the spot price, the time it was taken and the source (gold-api.com) inside the box.
It sets no cookies. Like the rest of Vault Drop, it counts page views with Cloudflare Web Analytics, which is cookieless. Spot prices load from gold-api.com in your visitor's browser.
Works on phones and in every current browser. The box is plain HTML, about 16 KB before fonts.
All we ask: keep the "Melt calculator by Vault Drop" line under the box. That's how people find us.

The code

Copy and paste

Paste it into an HTML block (WordPress: "Custom HTML"; Squarespace: "Code"; Wix: "Embed code"). Use the first one if your site doesn't allow scripts.

Start on a coin (optional)

Fixed height

<iframe src="https://getvaultdrop.com/embed/melt/" title="Coin melt value calculator" width="100%" height="620" style="border:1px solid #cdbfa6;width:100%;max-width:560px;display:block" loading="lazy"></iframe>
<p style="margin:6px 0 0;font-size:14px"><a href="https://getvaultdrop.com/melt/">Melt calculator by Vault Drop</a></p>

620 px tall, enough for a phone-width column with no scrollbar. Change the height if you like.

Auto-resize

<iframe class="vd-melt" src="https://getvaultdrop.com/embed/melt/" title="Coin melt value calculator" width="100%" height="620" style="border:1px solid #cdbfa6;width:100%;max-width:560px;display:block" loading="lazy"></iframe>
<p style="margin:6px 0 0;font-size:14px"><a href="https://getvaultdrop.com/melt/">Melt calculator by Vault Drop</a></p>
<script>addEventListener("message",function(e){if(e.origin!=="https://getvaultdrop.com"||!e.data||!e.data.vdMeltHeight)return;document.querySelectorAll("iframe.vd-melt").forEach(function(f){if(f.contentWindow===e.source)f.style.height=e.data.vdMeltHeight+"px"})});</script>

Adds a short script that fits the frame to the calculator, so there's no empty space on wide screens. The calculator only sends its height; the script ignores messages from any other site.

Notes

Melt is the metal value only. The box says so, and it carries our line: "Not financial advice. Verify all details with the official auction listing."
Coin specs come from official sources, cited on each coin page.
