My Approach & Contributions

Problem

Coin collectors often struggle to:

  • Keep accurate, up-to-date records of their finds.
  • Remember where they found certain coins or what they’re worth.
  • Organize coins by type, year, or value without cumbersome spreadsheets.
  • Stay motivated or engaged in expanding their collections.
  • Current digital tools feel sterile and data-heavy, with little sense of excitement or achievement.

 

Overview

King Arthur’s Coin Collection is a web + mobile app concept that allows hobbyists and professional numismatists (coin collectors) to catalog, track, and value their coins.
Inspired by the legend of King Arthur’s vault, the app combines collection management, education, and gamified progress in a refined, treasure-like experience

Numismatists:
Serious collectors managing hundreds of coins and seeking historical accuracy.

Treasure hunters & metal detectorists:
Users logging their field finds and market values.

Design Direction

Visual Style: Medieval-meets-modern — parchment backgrounds, golden accents, serif typography.

Color Palette: Deep browns, golds, slate grays, and muted blues.

Tone: Premium yet approachable; a collector’s vault meets an adventure log.

UI Components:

Illustrated icons (crown, sword, shield, coin)

Card-based grid system

Progress rings and badge icons

Subtle scroll-based animations

Design Process

Research & Persona Creation – Interviewed coin collectors and hobbyists to identify organization pain points.

Wireframes & Flow Mapping – Sketched the collection dashboard, “Add Coin” flow, and gamification UI.

High-Fidelity Mockups – Designed a premium theme balancing usability and thematic depth.

Prototype Testing – Iterated based on feedback emphasizing ease of data entry and visual clarity.

UX Goals

  • Simplify data input with smart defaults & presets.
  • Create delight through microinteractions and collectible animations.
  • Encourage user engagement with achievement tiers.
  • Balance aesthetic immersion with clear information hierarchy.
  • Design for cross-platform use (desktop + mobile parity).

The Results

Outcome

A high-fidelity UX/UI concept that turns a typically static data-management task into an immersive and rewarding collecting experience.
The result: A product that transforms the collector’s journey from simple record-keeping to treasure-keeping.
