A Lifetime Guarantee. No Fine Print.
We stand behind every item we sell with an unconditional, lifetime money-back guarantee — and 10% of our revenue goes to childhood cancer research.
The Guarantee
Our guarantee is simple and unconditional:
If any recognized authentication service determines that a signature on an item purchased from Penmark Authentic is not genuine, we will refund the full purchase price. This guarantee has no expiration date and is transferable to subsequent owners.
We do not offer this guarantee as a marketing gimmick. We offer it because we are confident — deeply, professionally confident — in the authenticity of every signature we sell. The guarantee is the logical expression of that confidence.
Certificate of Authenticity
Every item sold by Penmark Authentic ships with our Certificate of Authenticity. This document includes:
- Item Description — Full description of the signed item, including the celebrity, format, and photograph or album details.
- Authentication Statement — Our formal statement confirming the signature's genuineness, based on our examination and provenance verification.
- Guarantee Terms — Clear statement of our lifetime money-back guarantee.
- Contact Information — Direct contact details for Penmark Authentic, so future owners can verify the certificate at any time.
Our certificate is a general company certification — appropriate for the price range and nature of our merchandise. Every certificate is issued by Penmark Authentic and backed by our full lifetime money-back guarantee.
Shipping Standards
Every item is packaged with care appropriate to its format and value:
- Photographs — Shipped flat between rigid backing boards in a protective sleeve, inside a sturdy mailer.
- Vinyl Records — Double-boxed with corner protection to prevent seam splits and cover damage.
- CDs — Bubble-wrapped and boxed to prevent jewel case cracking during transit.
All shipments are fully insured for their sale value. We ship internationally to the US, UK, and EU with tracking provided.
Condition Standards
We describe the condition of every item honestly. If a photograph has a crease, we will tell you. If a vinyl sleeve has edge wear, we will tell you. Honest grading is inseparable from honest dealing.
For photographs and prints, we describe any visible defects including bends, creases, or surface marks. For vinyl records, we note both sleeve and disc condition using standard grading terms. For CDs, we describe the condition of the case, booklet, and disc.
Every eBay listing includes detailed photographs of the actual item you will receive — not stock images.
Giving Back: 10% of Revenue
We donate 10% of our entire revenue — not profits, revenue — to the National Pediatric Cancer Foundation through the eBay for Charity program.
The money is sent directly by eBay, ensuring full transparency.
The National Pediatric Cancer Foundation's Sunshine Project brings together leading researchers to develop less toxic, more effective treatments for childhood cancer. Every item you purchase from us directly funds this research.
"Every item you purchase from us directly funds research to eliminate childhood cancer. That's not a slogan — it's a permanent, measurable commitment."

Guarantee & Shipping — Frequently Asked Questions
Details about our lifetime guarantee, Certificate of Authenticity, shipping standards, and charity commitment.
What does your lifetime money-back guarantee cover?
Our guarantee is unconditional: if any recognized authentication service determines that a signature on an item purchased from Penmark Authentic is not genuine, we will refund the full purchase price. There is no expiration date, no fine print, and no conditions. We offer this guarantee because we are professionally confident in the authenticity of every signature we sell.
What is a Certificate of Authenticity for autographs?
A Certificate of Authenticity (COA) is a formal document issued by the seller confirming that a signed item has been authenticated. Our COA includes the item description, our authentication statement, guarantee terms, and direct contact information for Penmark Authentic. It is backed by our lifetime money-back guarantee. Not all COAs are equal — ours carries the weight of a named specialist dealer who stands behind every piece financially.
Can I return an autograph if I change my mind?
Items purchased through our eBay store are covered by eBay's standard return policy in addition to our own lifetime authenticity guarantee. For authenticity-specific concerns, our lifetime guarantee applies regardless of when you purchased the item. Contact us at mail@penmarkauthentic.com for any return or guarantee inquiries — we respond within 24 hours on business days.
Is your autograph guarantee transferable to new owners?
Yes — our lifetime money-back guarantee is fully transferable. If you sell or gift an item originally purchased from Penmark Authentic, the guarantee transfers to the new owner. This means the item retains its guarantee value regardless of how many times it changes hands. Future owners can verify any certificate by contacting us directly.
How are signed photographs shipped to prevent damage?
Photographs ship flat between rigid backing boards in archival sleeves, inside a sturdy mailer. Vinyl records are double-boxed with corner protection to prevent seam splits. CDs are bubble-wrapped to prevent jewel case cracking. All shipments are fully insured for their sale value. We ship internationally to the US, UK, and EU with tracking provided on every order.
How do you describe the condition of signed items?
We describe every item honestly and in detail. For photographs and prints, we note any visible defects including bends, creases, or surface marks. For vinyl records, we describe both sleeve and disc condition using standard grading terms. For CDs, we describe the case, booklet, and disc condition. Every eBay listing includes detailed photographs of the actual item you will receive — not stock images.
Why does Penmark Authentic donate 10% of revenue instead of profits?
Revenue-based donations are more transparent and impactful than profit-based ones. Profit figures can be reduced through reinvestment, expenses, and accounting decisions. Revenue is straightforward — 10% of every dollar we earn goes directly to the National Pediatric Cancer Foundation through eBay for Charity, with payments processed by eBay for complete transparency. This structure ensures our charitable commitment is meaningful and verifiable.
What happens if a third party disputes the authenticity of my autograph?
If any recognized authentication service determines that a signature on an item purchased from us is not genuine, we will refund the full purchase price. No time limit. No questions asked. We stand behind this unconditionally because our business depends on trust — a single inauthentic item would undermine everything we've built. Contact us with any concerns and we will work with you promptly.
