To convert League Medals into Gems in Clash of Clans at a 1:1 ratio, buy 10-medal utility potions from the League Shop and immediately sell them from your Magic Items inventory for 10 Gems each. Spending 1,000 League Medals this way yields exactly 1,000 Gems.
League Shop Potion and Hammer Conversion Rates
Only three items in the League Shop offer a direct 1:1 conversion rate: Training Potions, Resource Potions, and Clock Tower Potions. Higher-tier potions and Hammers cost significantly more medals but do not scale up their Gem refund values accordingly.
| League Shop Item | Medal Cost | Gem Refund Value | Gems Per Medal Ratio |
|---|---|---|---|
| Training Potion | 10 | 10 | 1.00 (Optimal) |
| Resource Potion | 10 | 10 | 1.00 (Optimal) |
| Clock Tower Potion | 10 | 10 | 1.00 (Optimal) |
| Hammer of Building | 120 | 100 | 0.83 |
| Hammer of Heroes | 165 | 100 | 0.61 |
| Research Potion | 20 | 10 | 0.50 |
| Builder Potion | 30 | 10 | 0.33 |
| Hero Potion | 30 | 10 | 0.33 |
| Power Potion | 30 | 10 | 0.33 |
Buying 30-medal potions to liquidate for Gems cuts your return by two-thirds because they sell for the same 10 Gems as a 10-medal potion. Hammers offer a higher lump-sum refund of 100 Gems, but their high medal costs result in a net loss compared to purchasing 10-medal utility items.
How to Convert Medals to Gems Step-by-Step
Because standard potion storage caps out at five per type, convert your medals in small batches:
- Clear existing potion capacity: Tap your Town Hall or Clan Castle, select Magic Items, and check your Training, Resource, and Clock Tower Potions. If any are at the 5/5 capacity, sell them for 10 Gems each to create space.
- Access the League Shop: Open the in-game Shop from your Home Village and tap the League Shop tab.
- Buy in batches of five: Purchase up to five Training Potions, Resource Potions, or Clock Tower Potions until that item reaches capacity.
- Sell the potions: Return to your Magic Items inventory, select the potion stack, and confirm the sale to collect 10 Gems per potion.
- Repeat as needed: Re-enter the League Shop and repeat the cycle until you hit your target Gem amount or exhaust your surplus medals.
When to Exchange League Medals for Gems
Exchanging medals for Gems trades upgrade-skipping efficiency for currency flexibility. Consider cashing out medals under these conditions:
- Unlocking Builder Huts: For mid-tier Town Halls lacking the fourth or fifth Builder Hut, upgrade timers are short enough that Hammers provide minimal value. Converting medals into Gems lets you purchase permanent builders directly.
- Buying Epic Hero Equipment: The Trader periodically offers missed Epic Hero Equipment (such as the Giant Gauntlet, Frozen Arrow, or Fireball) for 1,500 Gems. Liquidating medals provides a direct route to these items without waiting for event reruns.
- Funding Goblin Builder Events: Gems can hire the secondary Goblin Builder and Goblin Researcher during limited events, allowing you to run extra lab or builder upgrades at low costs.
If your Builder Huts are fully unlocked, key equipment is acquired, and village upgrades exceed 12 to 14 days, spend medals directly on Hammers of Building or Fighting instead of liquidating them.

The tips are practical and easy to follow.
This helped me understand strategy much better.
Nice guide. I am checking the other Clash of Clans articles next.
I wish I had read this before upgrading the wrong thing.
