Updated November 6, 2026 · Public MembershipOpen registration
Adults age 18 or older with a U.S. mailing address may sign up, accept the policies, and create a collector profile. Your public username identifies your listings; full name, email and mailing information remain private.
$15 for one year
An annual membership costs $15 USD and grants one calendar year of trading access. It is a one-time payment with no automatic renewal. A renewal begins after your existing access ends. Annual payments become available when live checkout is enabled.
Free introductory offers
A valid promo provides two or six free calendar months. Each account may redeem one introductory offer in total. Codes may be changed or disabled by Duke. Previously granted periods retain their end dates unless access is suspended for a policy violation. No card is required and free access does not become a paid membership automatically. At expiry, you can choose to pay for a year.
Trading responsibilities
Post accurate Have and Want listings. Have listings require clear front and back photographs. Review the condition and complete terms before both collectors accept. Each member is responsible for their shipping and performance. Membership does not guarantee matches, authenticity, delivery or the outcome of a trade.
Account rules
Follow the Terms of Use, Privacy Policy, Community Guidelines, Prohibited Items Policy and Shipping & Dispute Policy. Duplicate accounts, misleading listings and abuse may lead to suspension. Contact Duke about membership or payment concerns.
