Gold Coin Info and Tools Website

I'm looking to create an informative website about gold coins. The site should feature:

- Historical data about gold coins
- Investment tips and guides
- Current market prices

Additionally, I want a members login page where users can view their holdings and values.

Interactive features should include:
- Interactive gold coin calculators
- Gold and silver pricing charts
- Members-only access to buy metals online

Ideal skills and experience:
- Web development proficiency
- Experience with interactive tools and calculators
- Secure member login integration
- Knowledge of gold market would be a plus
