San Jose Giants 'REX' Mascot Baseball Card - First Edition 99

Era / Decade

1999 (Late 1990s); indicated by the '99' on the Rex logo and aesthetic style

Material

Standard cardstock with glossy finish and black border

Condition

Good to Very Good. The card shows some visible edge wear (whitening) on the bottom left corner and minor surface scuffing on the black borders. It appears to be kept in a plastic bag rather than a rigid top-loader, which may have led to slight curling.

Demand Level

Niche. Very low demand for general sports card flippers, but high interest for Minor League Baseball (MiLB) collectors or mascot completionists.

Resale Value

Estimated Resale Value

$5.00 - $15.00 (Depending on finding a specific mascot collector or Giants super-fan)

Estimated Retail Value

$1.00 - $3.00 (Original stadium giveaway or team set price adjusted for inflation)

Comparable Sales

Generic Minor League mascot cards typically sell for $3-$8. Rare or 90s specific team-issued mascot cards can fetch $12-$20 to the right buyer. No recent direct sales of this specific 1999 First Edition Rex found, suggesting scarcity.

Description

A rare vintage mascot card featuring 'Rex,' the green dinosaur mascot for the San Jose Giants (the Low-A affiliate of the San Francisco Giants). This is a 'First Edition' card from the 1999 series, featuring Rex in a white home jersey and sunglasses, diving for a ball. The card features a distinct black-bordered design with bright late-90s typography.

Key Features

First Edition marking; mascot specific (mascot cards often have a niche following); nostalgia for San Jose locals; cross-collectible for San Francisco Giants fans.

Authenticity Indicators

Correct printing patterns for 90s sets; specific team logos and mascot likeness; 'First Edition' gold text. Confidence: High.

Flaws to Note

Corners are not sharp (notable white touch on bottom left); slight edge wear on black borders which makes defects very visible; minor bowing/warping of the cardstock.

Selling Guide

Where to Sell

eBay is the primary choice due to its reach for niche collectors; COMC (Check Out My Cards) if you have a larger portfolio of cards; San Jose local Facebook Marketplace or Bay Area sports groups.

Selling Tips

Use keywords like 'Minor League Baseball,' 'MiLB,' 'SJ Giants,' and 'Mascot Card.' Take it out of the thin plastic bag and place it in a penny sleeve and rigid top-loader for professional presentation. Offer 'Standard Envelope' shipping on eBay to keep shipping costs low ($0.60 - $1.00) relative to the card's price.
