China- Sun Yat Sen - 50$ - Extremely Rare - One Copy Known Of This Rare Error Stamp.

Sorry not interested in selling my stamps maybe in 10 years, not now . Trying to build a decent stamp collection .

Ok I understand. But what about your stamp, can you tell me what kind of paper is yours.Very important for the value: 50cents or 200$ depends on the paper variety.Dr. Sun stamps should have something different to claim a value.Very interesting to check Interasia previous sales.They have a lot and actually you can see why the sale price.
Anyway, thank you for your reply.

@Patrasf

thanks for your contribution to the humorous side of this forum. I do appreciate funny things.

but my smile tend to go away when people try to fool other people for money.

Sorry, I do not understand your comment.
I offered to buy, not to sell.If Floortrader wants to sell, maybe I will buy. And his response was very honestly said, his not a seller.

For INTERASIA-HONG, is public site, go and see.
If you only buy 50 cents stamps, that's ok, is your choice.
Personally I had a collection of more or les 12000 stamps and I' m selling in ebay the balance of 400-500 stamps left.Selling price is as per CATALOG and also multiple research on different auctions houses.
So maybe you can have more interesting comments which can honor this site.
Best regards,
