Black leather bifold wallet with panda sticker

I lost my black leather bifold wallet yesterday around 3pm near the Hy-Vee on Hamilton Boulevard in Sioux City. It's pebble-grain, about 4.25 by 3.25 inches, with a small coin pocket and a panda sticker inside the card slot. It holds my driver's license, two credit cards, and about $60 in cash, and there's a coffee stain on the back with a crease along the spine. This wallet has sentimental value—it was a Christmas gift from my mom, so I’d really appreciate getting it back.

Gray canvas tote bag with camera gear

I lost my gray canvas tote bag yesterday around 3pm outside the Sioux City Public Library on Douglas Street, near the little cafe on the corner. It's a medium tote, about 14 by 12 inches, with a black shoulder strap and a small faded Coach tag on the zipper pull. Inside you’ll find a compact digital camera, a spiral notebook with a fox sticker on the inside pocket, and my brown leather wallet with a few cards. The bag is worn but sturdy, a couple of scuffs along the bottom. It holds a lot of sentimental value; it was a gift from my grandmother. If anyone found it, please message me—really hoping to get it back.

Blue US passport (Passports) lost in Sioux City

I lost my blue US passport yesterday around 3pm in Sioux City. It was tucked in a brown leather passport holder with a small sunset sticker on the back, and the cover shows the gold crest and 'United States of America' in gold. I last had it after grabbing a coffee at the Starbucks on Main Street, then walked toward the downtown library steps near 4th Street. It’s crucial for a trip next week and has sentimental value because it was a gift from my grandma. If anyone found it, please email [email protected]—I’d really appreciate getting it back.

White Pyrex mixing bowl with blue floral trim

I lost my white Pyrex 9-inch glass mixing bowl yesterday around 3pm. It was in the downtown Sioux City area, around the Hy-Vee on 4th Street, near the riverfront by the old train depot. It has a delicate blue floral border around the rim and a small chip on the lip from a clumsy drop. The bottom still shows the Pyrex stamp. This bowl was a gift from my grandmother, and it carries a lot of sentimental value - really hoping a good soul comes across it. If you found it, please drop me a message; I'd be forever grateful to get it back.

Blue Giro bike helmet with reflective stripe

I lost my blue Giro bike helmet yesterday around 3pm. It's a size M, glossy royal blue with a white reflective stripe along the edge and a small scratch on the left shell. The inside padding is gray and a little worn from daily rides. I was cruising the Sioux City Riverfront Trail, near the 4th Street pedestrian bridge by the city marina when I must have dropped it near the bike racks. It felt like a practical safety piece and it also carries sentimental value; my sister gave it to me last year to celebrate finishing my first half-marathon. I really need it back so I can keep riding safely. If you found it, please reach out. I can offer a small reward.

Gray trail running shoes with neon orange laces

Found a pair of gray trail running shoes this afternoon around 1:15pm behind the downtown library on Main Street, near the riverfront bike racks. They’re men’s size 10, by Nike, with neon orange laces and a small blue stitch on the heel tab. The left shoe has a tiny scuff on the toe, and there’s a faint logo impression on the side. I picked them up because they looked recently worn but not soaking wet, sitting in a damp patch by the bench. If this is yours, reply here or email me at [email protected] to arrange pickup.

Found compact silver Korg microKORG synthesizer

I found a compact silver Korg microKORG synthesizer this afternoon around 2:15pm outside a small music shop on 5th Street in downtown Sioux City. It's in good condition, with a few light scratches and a tiny dent on the bottom edge. It has 37 mini keys and a built-in vocoder. It came in a black soft case, with a blue USB cable tucked inside. On the back there’s a red sticker with the initials 'J.S.' This looks like gear a serious musician would miss, and I’d hate for it to disappear again. If it’s yours, please get in touch here or email [email protected] with identifying details to prove ownership.

Blue Mega Bloks city toy set found near library

Found a blue Mega Bloks city toy set this afternoon around 3:45 pm in the parking lot behind the Sioux City Public Library on Court Street. It’s all in a small yellow tub, about 8 inches across, with blue and red bricks and a couple of little white wheels. The tub lid has a faded sticker of a cartoon lion, and one blue 2x4 brick has a tiny heart-shaped scratch—easy to spot. The bricks look clean but dusty, and the set seems complete enough for a kid to build with. If you recognize this, message me and I’ll get it back to you.

Gray Nike running shoes with orange laces

I found a pair of gray Nike running shoes this afternoon around 2:15pm outside the Sioux City Public Library on 4th Street. They're size 9 men's, with a white sole and a coffee stain on the left toe, plus one bright orange shoelace tied in a double knot. The right shoe has a small scuff near the heel, but otherwise they're in decent condition. I’d really like to help get them back to their owner—if these belong to you, reply in the app and we can meet near the library to verify ownership.

Black 12-inch skillet with lid

Found this afternoon around 3:50pm behind the Main Library on 4th Street in downtown Sioux City. It’s a black 12-inch T-fal nonstick skillet, comes with a clear glass lid that has a small steam vent. The handle is wrapped in a bright blue silicone sleeve that’s seen some wear. There’s a tiny chip on the outer rim and a few scratches along the bottom from regular use. The lid seals well and the pan cleans up nicely. If it’s yours, drop a note here and we can arrange a safe pickup.
